Living off tips is ridiculously hard and unpredictable. I started working in restaurant/bars when I was just 13 as a bus girl. I worked my way up to hostess and waitress. I was sexually harrassed on a daily basis and just thought it was normal because I was so young. Now, I am a doctor of physical therapy and when I think back to the times I was cornered by a customer and had to make them happy however possible, it makes me sick and sad.
