I've booked an appointment at quite a fancy salon in London for a couple of weeks' time. I've been having some hair issues and I need to start taking better care of it. The thing is, it's way way more expensive than what I'd usually spend. The cut and colour are going to come out at nearly £300! I'm justifying the expense as a worthwhile cost that could save further hassle down the road from going to somewhere cheap. The last place I went ruined my hair.
I imagine I'll be expected to tip on top of that, and it's stressing me out, as 1) I can't really afford to and 2) I have no idea how much is appropriate. The last time I went to an upscale place, they asked for 20% on the machine, which just felt mad. Would leaving an extra £10-15 look stingy? Would it be better not to tip at all? Is tipping mandatory?
