Yes i have had to deal with them, out down town their a nightmare, they knock your drink out your hand or whatever, ends up in a little scrap maybe, never hurt anyone. Bit of fun, all part of the process of been young in my opinion.
I love Hardcore music, its my life, yet i love full on screemo stuff, R&B, everything else. I certainly don't know what club you Bouncer on, but a decent Hardcore club does not have that kind of stuff on.
I know alot of chavs who are really nice people, thats why i am far from biased against them.
