It's busy. It's hot. And honestly I had probably the worst possible shift. The graveyard. 11pm to 7am. Yes, I am aware that I did this to myself, but I needed the extra income so there I was, "Welcome to Denny's, how many are in your party?" I learned to definitely not judge a book by its cover and to be kind even when you may want to cry.
The management varied by day. Some I liked, some I didn't.
I didn't have many co-workers, as late night shifts get to work mostly by themselves, with a cook and sometimes a dishwasher. Unless it was the weekend.
Hardest part? Having to deal with the humiliation of dropping something like food, or having to bring food back because it wasn't made right. And then having the customer not tip you, or blame you when it had nothing to do with you.
I did enjoy the quite times and customer interactions. You meet some interesting people at 3am at a Denny's.
