Three went a bit mad.

One really confused me. She took my call, told me where she was, opened the door, showed me to the room. 10 minutes later she came into the room and went mental that I should have made it clear I was booking her.
I didn't get into it with her as after her rant she became relatively normal. Scary but normal.

Another lady a long time ago completely ruined an appointment as she nearly became hysterical because I put my clothes in a ball on the floor. She slammed them onto hangers and hung them up. Then proceeded to literally jump up and down on me. Horrible experience. I just wanted to get out of there.

Finally one lady became quite upset because I didn't dry myself properly. Obviously it wasn't me and some other issue had upset her. She insisted I continued with the appointment. My mood was ruined, I only did her because I felt sorry for her
