Irritated, annoyed and wanna cut all her hair off. (ok no I won't but just saying)

I feel this way most of the times when I stepped out of a salon. I seriously don't get how difficult it is to cut as your customer wished. Ok granted it might be difficult when they want it to be the exact same style as those in the magazines and whatnot but hello, I'm just asking you to do a trim, and I specifically told you 1 inch. But you insisted that 1 inch is not enough, it have to be at least 2 inches. Fine, so I agreed, albeit very reluctantly. When she was finally done, and I wore my glasses, I hated what I saw. The thickness of my hair was half of before (or maybe lesser), because she layered and thinned it by so damn much, it freaking looks like a (shape of a) jellyfish where the top is so thick and the bottom is so thin. She was so happy that she cut off all my orange parts when I tried to tell her my hair was too thin...DID I EVEN SAY TO CUT OFF ALL OF THEM ? (I knew if they were to be all gone, my hair would be way too thin and short hence I did not mention for her to do that.) I don't get why can't she just stick to what I said, or does she love cutting my hair so much ?!?! Argh, annoyed. Now I've to wait for a month at least, to let it grow back some of the thickness :(
