The only things I learned at my Italian restaurant job were 1) NEVER work at a family-owned restaurant when you are not a member of said family, 2) pizza dough can be used to make large replicas of naughty parts (the owner did that, not us), and 3) it can be very invigorating to tell your boss off on your last day of work, especially when she shorted you shifts and then tried to get you to work one more at the last minute. I told her that maybe if she got off her big fat butt and did some actual work herself they wouldn't be short-staffed. Her husband (and the owner) was standing right next to me dying laughing. I was very proud of myself.
