For my first similar job at McDonald's, I thought the pay was crappy but all I had to do was stand at the counter, take orders, count change, and hand the food over. I started on the closing shift, not realizing the significance and they put me on the grill flipping burgers. As we closed the doors at the end of the night I thought it was time to go home. They asked me to take the trash out and I understood the necessity.
Then I had to wash every damn pan, dish, pot, rack, and every other damn thing that touched food that day in extremely hot water that burnt my hands. Oh, I was mad. It seemed like they brought the whole damned restaurant back for me to wash. Finally, two hours after closing the dishes were done and I could go home, at 2:00AM.
I stayed on with the work but that was a nasty surprise for that low, crappy pay that I thought was barely enough for my time to stand at the counter.
Moreover, that was my schedule every day, the closing (and cleaning) shift. There were other people who worked mid-hours that neither opened nor closed and I thought that was unfair.
IMO, those closing shifts should be paid at least time and a half, preferably double time. More work is done in the time after the restaurant closed than while it was open and I hated that.
I then joined the Navy after high school and was surprised at all the cleaning I had to do. That seemed to be my whole job for the first couple years, cleaning up after everybody else.
Needless to say, this was excellent motivation to use the GI Bill to earn an education and enjoy the rigors of a real job as a respected knowledge worker in a comfortable office. May you do the same.
