OK, I've never figured this one out.
I get that you're supposed to tip.
What I don't get is how much and just how. As in when do I do it, who do I give it to, what do I say? And if I get a £30-40 wash and cut at a salon, how much tip?
Other option is a home hairdresser, they charge less does that mean you tip more or less or not at all as they keep all the money and can charge what they like in the first place?
I've been getting my hair cut at the kids hairdressers with the kids and just telling them to keep the change, and I'm not sure if that's even right - sometimes they've pressed me to take it anyway. Thinking I'd like to get a proper grown up cut now and I don't want to offend. Help oh wise ones!
