You must be picking the wrong Thai ladies.
All the ones I've let pick me seemed happy enough with their choice.
Walk in, sit down, order a beer, and let the girls approach you, works every time.
Ways to have an epic fail, demand the one hiding as far away from you as possible, order a soft drink, arrive with a bunch of drunk mates, don't be rude to the fat one that tries to choose you when you reject her.
