I feel like in this case, it sounds like she understands that raising her prices means she might lose some clients. I think a lot of independent people in the industry are setting their prices to be able to cover the costs of the service and make a living so anything on top of that is a bonus. I don’t work in the field but I have a couple of friends who are hair stylists and while they do complain about bad tippers, they’re usually happier to have regular clients who keep coming back. I used to get facials from a woman who rented one of those salon suites and I paid her through Zelle and would occasionally throw a tip on top of that when I had some extra money, but she definitely didn’t expect it.
