I prefer going to the dentist to getting a hair cut. My dentist is smiley and friendly but our exchange is brief, just the way I like it. With the cleaning, I just lay back and let a lady clean my teeth. She doesn't talk, just works. I like that, I'm paying her to clean not chat.
Hairdressers on the other hand, just don't like silence. They love to ask pointless questions, as if we NEED to get to know each other. Maybe that makes me a snob, but getting to know someone is very difficult, tiring and quite a long process. I need to know that there is something in it for me. With small talk, there's nothing in it for me, I just feel like I have to talk in order to be polite when they are asking me questions.
The thing with hair dressers is that they are very superficial, judgemental and can be quite mean. I realise that's not how they all are, but I can sort of size them up in a couple of minutes. What I really find annoying is how they have to always comment on things about your hair. Like, one girl asked me if I got a hair cut very often (it was very long at the time, as I had been avoiding a cut for a long time). Another said that my hair was thinning on top and it made me feel so uncomfortable. Now I'm obsessed over the thinning, as a female this is devastating. One guy who cut my hair did a terrible job, and when he was done he sarcastically said "well, that looks better! Just a LITTLE bit though, just a little!".
The last time I had my hair done it was ok though, as it was my sisters friend and she was very gentle. I didn't mind talking to her either because I have met her at parties before so it didn't feel like a waste of time. I've waited for 25 years to get someone decent to cut my hair. That and she did a great job! I actually felt like a normal person when I left the salon!
