I had a wax done while I was pregnant and no longer able to see to manage things myself. The staff was great, but it took longer than normal because I could not lie flat on my back. The receptionist charged me extra because the staff took longer than she decided was normal. I was not told that this would happen and perhaps wouldn't have chatted with the staff person after she was finished had I known I was paying for that conversation on top of the service.
I haven't gone back, yet.
