If you are by nature an ugly git, then the locals will treat you as nicely as your wallet allows.
If you are like me, naturally handsome and well endowed with a confident attitude and takes no BS, then you will be treated infinitely worse.
I think in Thailand it is better to be old, ugly and rich than good looking, confident and poor.
By Thai standards I am relatively well off, but I don't really flaunt it (anymore). I never tip, dress normally, don't drive a flash car and only carry in my pocket what I need to get me through the day.
