The win taxi riders are fine until you find one that is a nutter. I shopped in Central last week and used the first win setup on the left on beach road.
I always give the destination, jom tien, then ask the price. They said 100 baht, I agreed but then they grumbled and said tuk Mark. (too cheap) the rider then took off like a maniac. Almost threw me off the back of the bike.
These guys are fine until they have some mad grievance and then they are crazy. I stopped the ride early with no tip.
