how they make u return
The most important part of any restaurant of course is the cook. Even though you don't always see them they still play a huge roll. Without a good cook the food would either be gross or non existent. the cooks also make your plate look pretty.
On the other hand my favorite job is the cashier/bus boys. They make you experience fun and make you feel welcome. they also have to be trusted because they have access to the money and have to know how to give the right change
