While a student I worked in 'Horeca' for years as a bartender in a disco/bar. Worktimes from 22:00 to 5:30, minimum wage, and the tips weren't great.
It did have some good side effects in terms of money/going out:
1) I was making some money that did not require me skipping classes!
2) I worked in the weekends so I wasn't actually going out myself, thus spending money, but did get the whole 'going out' atmosphere.
3) For the first few years I worked there we were allowed to drink on the house during work, as long as it didn't affect your performance at work. Really helped the festive mood!
