heh, speaking of haircuts this brought back a memory. This was back in my 20s when I was still good looking. I went for a haircut near the city center of Kuala Lumpur one day, and was pretty much sexually assaulted.
Now if it was a cute gay guy I wouldn't have minded, but unfortunately it was a woman. She kept me in that chair for about an hour, basically gave me a free massage along with the haircut, while constantly telling me to come to her place some day for what she called "enjoys". She'd groan in my ear while whispering, "I like to do it in the backside", and things of that nature.
My god, that was the most horrific haircut of my life.
Back on topic, if I can remember correctly haircuts in Khon Kaen were generally 60 baht, so 80 baht with a tip.
