Pre-paid for two girls' cuts on the app and told halfway through the first that the second would cost an extra £15 because her hair was long. This should have been discussed before anything was started so I could have said, "No, I'm not paying £50 for a child's haircut." Had to agree, as I was on the spot, and was later refunded. But I don't agree that cutting a girl's hair from "below bra strap" length to shoulder length is "more work". It was a hair cut, period. Not going back.
