It's never really been a problem for me. I don't tend to go to really big scummy oceana-esque clubs these days, and even the ones that verge on that, I don't really get involved in busy, sweaty dancefloors. Even at the age of 18, I've accepted that I'm way too lanky to ever look good dancing.
I tend to just stay near the bar, chatting with friends, enjoying the music, talking to a girl or two. I'm not nearly as likely to get vodka and cranberry juice thrown all over my nice brogues in that situation. =)
