Are you a cook, or a waiter/bartender?
Is it a corporate restaurant, or in independantly owned place?
Working the frier at a bull-shit fast food place my be kind of a dead end.
Working at the best steak house or sushi place or sports bar in town may open some doors.
Serving and bartending, you get a bunch of cash, plus you talk to a lot of people. You can make connections, meet people, and just "learn stuff" in general. Usually other people working in the place will be college students, so you can get info about the local schools from them. Talking to customers you can learn about jobs, carriers and industries you never knew about. If you really make an impression, you may even get some kind of job offer.
If you work in an independent place, you can learn a lot from the owners. Watch how they interact and do business with distributors, vendors and liquor representatives. You may see some kind of job you're more interested in. Or some kind of opportunity to develop a business of your own.
Also, you're around lots of young girls, which is good.
Finally, and I can't believe nobody mentioned it; X-BOX TIME IS OVER! NO MORE VIDEO GAMES! Spend that time lifting, or drinking beer and gambling.
