When it comes to tipping, how do you determine if/how much you tip?

I work at an upscale wine bar. Most of our customers are middle aged to elderly and are normally well-off, otherwise they wouldn't be leaving their Jaguar in our valet while buying our $80 bottle of wine.

The most I've ever been tipped is 10%, and that's only happened to me a handful of times. For the most part, I don't get tipped at all. On an average night we serve 400 people and about 20 of them leave tips of around 2-3%. This does not just happen to me, but every one of my co-workers.

I do agree that tips should be earned and that you need to do your job well in order to receive tips. I can see how some of my co-workers end up getting stiffed on tips, but most of them are great bartenders and servers. Personally, I've only made three mistakes in the last two years regarding orders. I always work my fastest, though sometimes my speed depends on the person working behind the scenes, which slows me down. I am currently on bar because I can make and serve drinks faster than anyone else there.

This situation makes me curious about different people's tipping customs. I always leave at least 15%, even if the service wasn't great, 20% for average/good service, and I usually go 22% if the server was awesome.

The way tips work at my place is that at the end of the night we pool everyone's tips and divide them equally. It doesn't matter if I'm just pouring wine or if I'm serving food, I make a percentage of the combined tips.

Last night, everyone left with 50 cents. That's a combined $3 over the course of a night.
