Having lived here in Patong now for over one year, i can report zero negative experiences with any Thais. I go out regularly but never get totally pissed and always am polite as if I were a guest in someone's home - I am.
The only unpleasant incident was totally my fault when I went to the wrong vendor's stall on floor three at Jungceylon with a complaint over an item i had purchased. Profuse apologies on my part and some words in Thai from my lady quickly got it back under control.
Everything I observe in Patong tells me that demeaning, rude and alcohol fueled ignorant behavior from tourists results in most negative Thai behavior. it's amazing to me how difficult it is for tourists to do a quick currency conversion and remember that often disputes are over $7.00 USD, not $200.
As previously stated, behave like a guest, be easy going, friendly and pleasant to ensure a fun time during your stay.
And always, always, respect the ladies. The reward is beautiful memories for life.
Of course, one caveat - don't rent a jet ski.
