And I don't like straighteners.
Why can't they just do a normal blow-dry anymore? It seems that whether you want your hair straight, curly or wavy, the straighteners come out. I feel like the hairdresser is cheating a bit, there used to be skill involved in a blow-dry.
Straighteners damage your hair and I don't want then used on my hair.
The hairdresser asked me at the beginning how I wanted it dried, I said "just a good blow-dry please", she then said "okay then shall I go over it with the straighteners or curl it?" I said "no thank you". Then she did it anyway. 
And I know IABU because I didn't tell her to stop. I just sat there, made a face, then didn't leave a tip.
And, they always tug really hard on any knots, it hurts! I need to find a good hairdresser.
