Mr. Krabs is commonly known as the greedy founder and owner of the Krusty Krab restaurant, where SpongeBob works as a fry cook and Squidward works as a cashier. The restaurant's success is built on little competition and the popularity of the Krusty Krab's signature sandwich, the Krabby Patty, the formula to which is a closely guarded trade secret. Mr. Krabs frequently exploits his restaurant's popularity, engaging in price gouging and charging his own employees for use of the building's services.
