My appointment was at 11:45. I'm still waiting to be seen. My hairdresser has also said they're unable to do what I booked as they're double booked, so can only do half of what I want (have to leave my roots and can't dye). I always, always tip at hairdressers and restaurants, I usually give her £20 tip for a £90 appointment but I'm really annoyed, I'm going out tonight and wanted my roots and colour done, plus I'm still waiting to actually be seen. I booked for roots, dye, haircut and blow dry, but they are only able to do cut and blow dry. AIBU if I don't tip today? I feel bad but I'm really annoyed at the same time.
