3. People in the service industry deserve respect
Servers and bartenders are your kindred spirits. The work you do may be a little different, but oh, the assholes are entirely the same. Revel in your worst customer stories and enjoy the camaraderie of working a shitty job. At best, it's only temporary and you'll all soon move on to other things, and when you do, you will understand what it's like, and you will tip well. At worst, meet your new drinking buddies. Because you will probably be drinking a lot. But on the bright side—drinks will be very, very cheap.
