Actually, your hours as a bartender go into the wee hours of the morning, usually. When I was a bartender the bars closed at 1 or 2am, and then after cleaning up and balancing my register it would be 4am or so by the time I was home. I had a hard time with sleeping when everyone else was working or going to school, especially since on the opposite days I got up and went to school, but I managed to get used to it.
