I think we know what the real picture is - my anecdote from 1991, paully's from the recent past and yours from now - all male teachers who have done it, rather than a female who thinks she knows
and I was going to add that the fact that my subject was geography wasn't the main reason my overseas experience was viewed as positive and it was rather my having lived and worked overseas and experienced students of other cultures, etc.
Let's make it quite clear - TEFL experience, in Thailand or anywhere else, is viewed by educational employers in the West as a positive thing.
If your personality isn't deemed suitable it doesn't matter whether you've been living in Bangkok or Bournemouth.
