On his lunch break, Squidward encounters Squilliam Fancyson with a group of his fans. Squilliam asks Squidward what he has "accomplished" since high school, Squidward, panicking, tells him that he owns a five-star restaurant.
Squilliam tells Squidward that he and his friends will come to his restaurant that night, and Squidward is very shocked. He begs Mr. Krabs to let him have control of the Krusty Krab for the day, and when he explains that Squilliam's coming, Mr. Krabs accepts because he knows that Squilliam has money.
Squidward attempts to train his employees to turn the Krusty Krab into a fancy restaurant, including Patrick, who thought that he was joining the corps and is given the job of collecting the hats. SpongeBob, who doesn't yet know how a waiter works, is the waiter, and Mr. Krabs, who says he once served on the S.S. Gourmet, is the chef. However, things do not go well; Patrick is beating up the hat rack because it won't "give" him its hat, Mr. Krabs makes terrible food and says that he worked as a janitor on the Gourmet and was the head chef on the S.S. Diarrhea, and SpongeBob can't handle the copy of "How To Become A Fancy Waiter in Less Than 20 Minutes" that Squidward gave him. Squidward tells SpongeBob to clear his mind of "everything that doesn't have to do with fine dining and breathing". SpongeBob's mind, which is metaphorically portrayed as an office, is operated by smaller SpongeBobs. Their boss's assistant tells them that he's just got an order: Dump everything that isn't about fine dining. They begin to get rid of all documents, which represent SpongeBob's knowledge, until SpongeBob just stares into empty space and doesn't respond to anything.
Squidward runs outside and bumps into Squilliam, who is just about to enter. They both go inside, and see that the Krusty Krab has been transformed into a very fancy five-star restaurant. After sending all the customers to their tables, SpongeBob tells Squidward that he did all of this, and that he has tied up Patrick and Mr. Krabs in the kitchen. After his meal, Squilliam admits that he is impressed and asks SpongeBob what his name is. However, SpongeBob cannot remember his name, having discarded it along with everything else, and inside his mind, all of the little SpongeBobs are trying to find his name, which ultimately results in his brain snapping in half. SpongeBob goes insane, mindlessly spilling food on patrons and grating the posteriors of others. Mr. Krabs and Patrick run out of the kitchen, still tied up, being chased down by the appetizer the former made earlier which has turned into a monster. With this, the fancy restaurant environment is destroyed and the Krusty Krab's true nature is revealed. Squilliam finds out that Squidward actually is a cashier, humiliating him. However, Squilliam then "confesses" that he's also a cashier too and that he lied about being rich to upstage Squidward and beat him. Squidward asks if this is true, but Squilliam reveals that he was just kidding and he really is, "filthy stinkin' rich!" He and his crowd leave the restaurant to ride in his "balloon/casino," leaving Squidward dejected and defeated once again, but not before Mr. Krabs comes in and plays him a sad song in the World's Smallest Violin, which annoys him and makes him angrily request to leave as the episode ends.

- This episode is available on the UK version of SpongeBob Goes Prehistoric VHS.
- This is the second appearance of Squilliam Fancyson, the first being in "Band Geeks."
- In the Bahasa Malaysia dub of this episode, when SpongeBob greets the customer, what he says translates to "Your butt want to eat rice?"
- In the Spanish Latin American dub when Patrick says 'you mean like a weenie, okay' he says "...como se fuera un mayordomo, de acuerdo." (as if I were a butler, I agree). 
- Fred is seen wearing the same clothes as SpongeBob: brown trousers, black belt, and a white shirt.
- This episode makes two references to its sister episode, "No Weenies Allowed." One is that Patrick acts like a "weenie," which is a reference to the Weenie Hut franchise. The other is that one of the things that is thrown out is "Spice Garden tips," which is a reference to the line "I'll have you know I stubbed my toe last week while watering my spice garden, and I only cried for twenty minutes."
- Eight parts of this episode have become popular on YouTube (the most out of all episodes):
- Patrick saying "May I take your hat sir?"
- Squilliam, Squidward, and the fishes saying "Hommina."
- Squidward imagining Squilliam as a hot underwear model and saying, "Oh no, he's hot!"
- Squidward frighteningly saying "T-t-t-t-t-t-tonight?!"
- Mr. Krabs playing the world's smallest violin.
- The scenes with the Clever Visual Metaphors for the Abstract Concept of Thought.
- Mr. Krabs yelling "Run for your lives everyone! It's the Appetizer!"
- SpongeBob complaining about memorizing facts about fine dining.
- Apparently, Patrick wants to join the Marine Corps.
- When Mr. Krabs messes up the peas and the appetizer and Squidward interrogates him, the two speak as though Mr. Krabs had told Squidward that he was the "Head Chef" on the S.S. Gourmet. This is not true, as their first conversation regarding the S.S. Gourmet was Squidward merely asking Mr. Krabs if he had "once served" on it and then jumping to the conclusion that he had been the chef.
- Most suitless Bikini Bottomites wear clothes in this episode.
- When Squidward asks SpongeBob how he transformed the Krusty Krab, Squidward addresses SpongeBob by name. SpongeBob replies as if he already knows his name. However, towards the end of the episode, when Squilliam asks him his name, SpongeBob's name is "thrown out" of his mind. This conundrum would put a major loophole in the entire storyline.
- When Squilliam "admits" he is a cashier, Mr. Krabs is seen wearing a tuxedo rather than the outfit he had worn throughout the episode. This also happens at the very end.
- This episode was paired up with "The Thing" during the Massive Monster Mayhem Marathon.
- When Squilliam and his party are at Squidward's five star restaurant, SpongeBob seats them immediately while in reality he should have called ahead as restaurants that achieve a five star rating tend to be fully booked.
- "Hommina hommina hommina" is Ralph Kramden's catchphrase in the 1955 TV show The Honeymooners.
- The world's smallest violin that Mr. Krabs plays might be a reference to the 1992 movie Reservoir Dogs when Mr. Pink is arguing about tipping the waitress, and Mr. Pink says, "You know what this is? The world's smallest violin playing just for the waitresses."
- When Squidward turns his head over to Squilliam, he is coming to the left, but when Squidward puts his hat in the bin, Squilliam is to the right.
- When Mr. Krabs plays the world's smallest violin after the Krusty Krab reverts to its original self, his eye stalks are white instead of pale green.
- Judging by the width of the How to Become a Fancy Waiter in Less Than 20 Minutes book, it should take longer than 20 minutes to read the entire manual.
- Before Squilliam enters the restaurant, the windows of the Krusty Krab are visible, but inside, there is wallpaper covering the windows.
- The appetizer destroys the door to the kitchen, but it is shown to be intact at the end of the episode.
- When Squilliam arrives at Squidward's "five-star restaurant," it is sunset, but when he is eating his meal, it is nighttime, and when Squidward says "Would you get out here?!" it is supposed to be night, but instead it takes place during the day but dark.
- The Krusty Krab turns normal when it was already decorated.
- SpongeBob knew nothing except for fine dining and breathing, but manages to tie and gag Mr. Krabs and Patrick.
- When Patrick and Mr. Krabs are bound and gagged in the back, Mr. Krabs' legs are not tied but his eyes are. However, when he comes from the kitchen, it's the other way around.
- Some of the people in Squilliam's group do not have bottom halves.
- When Mr. Krabs comes out from the back, he has no arms. It is unlikely that his hands were tied behind his back, because before that, it shows that SpongeBob tied his hands on his stomach.
- Finally, at the end of the episode, when Mr. Krabs walks up to Squidward to play the world's smallest violin, he is simply just dragged there, with his legs not being animated.
