And one for you being in your line of work It's not customary to tip bar staff here, it is in the US and expected - try going in that bar again otherwise! I have walked out of bars there without tipping but only if I'm not going in again the next night!
if only my punters....erm customers didn't do the same! i dont exect tips, just nice when people give em,no matter how small, rememememememember that mate
