From Humble Beginnings
This section explains how Mr. Krabs made the history of the Krusty Krab. He was always a financial wizard from childhood to the present. Krabs fought in a war as a Navy officer, but it was depressing for him. Later, he acquired a bankrupt retirement home. After receiving it, the Krusty Krab was born.
The Krusty Krab Today
Throughout the years of service, customers demand more from the Krusty Krab to satisfy their needs. That is why they have new technology, including spatulas, ketchup packets, and ice cubes. Krabs has a fear of robot overlords, thus allowing limited technologies. It is also stated that modernization is the heart of the Krusty Krab while employees serve like the liver and gallbladder of a body.
As for safety of health, there are a set of strict personal hygiene guidelines. A person's hands must be very well washed, their boots must be polished, their face must be clear of any blemishes or boils, and their hair must be neat.
