When I lived in the US, it was a given that you tipped your hairdresser (a very healthy 15% or something ludicrous).
But I don't know what the rule of thumb is for hairdressers in the UK. Personally, it irritates me having to pay a tip on top of forking out a small fortune to get my hair cut. I mean, I do PR for clients and I charge them for the service and I don't expect a tip too.
But on the other hand, if it's the done thing to do, then I don't want to be mean. So a) are you supposed to tip your hairdresser and b) if so, how much?
thanks
