I just arrived a hour or so ago (October 31) in Bangkok with my non imm o-a multi entry visa that I purchased back in June. Things worked exactly as they have the past seven years - no questions, virtually no conversation and the Immigration officer stamped me in for another year.
It was interesting in that was the first time ever someone was there checking the baggage claim tickets. We have never, ever had anyone express any interest in our many prior visits.
