I liked making extra money from tips, interacting with customers, and spending time with coworkers.
What I wish was different
I wish there had been less pressure to take on more shifts and hours than I wanted. I wished I had more free time and less time working.
Advice
It's not always easy working with customers all day but in general, many more people are kind than mean. Also, while it's nice to help out coworkers by picking up their shifts, stand your ground and don't take on more than you can handle.
