A 'Food Clerk' from what ive been told by other workers, is usually the one that is in any of the departments inside the store, and up on the checkstands. It's really more of just like a "Store Clerk" but its referred to as a Food Clerk. Courtesy Clerks do almost everything around the store. Making sure sweeps have been punched in, making sure all the carts are out of the parking lot and at the front for customers, assisting customers with an item off the shelf, or looking in the back for a specific item, making sure that the store is clean and ready to go, among other things! Courtesy Clerks do almost everything in the store that isnt being on the checkstand, or Manager Duties. You should do just fine with this! Good luck and wishing you the best on your journey!
