In my time at Chick-fil-A, I gained a lot of experience, but that's about the only thing I got from there. Your coworkers are rude to you even if you are the nicest person, the managers are not fair, the hourly pay is unreasonable, and expectations of the managers thinking you can do four jobs at once is ridiculous.
What I did on a daily basic was, to make sure everything was up and running perfectly fine before opening hours or make sure everything is clean and put up for the next day at night time. I would also make sure that my team was in the best shape and if they needed help I was there to help them, and too also make sure we never ran out of food storage. End of every shift to make see what food waste was and the cost of it.
