I would say that you cant bata with Thai's like you can in Bali with the Balaneese because the first price isnt as inflated as in Bali.

Thai people on a whole are honest people more so i have found than Europeans so if you try to bargain to low or too much they will say no with a smile.

You will know within a day weather you are getting ripped of big time but the small ones dont really matter,after all even when you get ripped of a little bit it is so cheap anyway that most time it doesnt seem to matter.

If you want to have fun while bargaining,when you are given a price just say"Cow sip cow baht" I dont know how to spell it in Thai but it means 99baht, this usually gets the vendors laughing and every time they see you they will remember and say "Cow sip cow".
