As a foreigner, are you meant to return the Wai when service staff Wai you first.
I’ve seen some foreigners just either smile, walk off, Wai back, one guy did a Wai and it almost looked like an army salute
I’ve checked the post history here and even then some people seem to say yes definitely and others say NO you’re a foreigner, you’re not expected to do Thai customs. What is more appropriate?
