When this happens in cultures without this tradition, I find that both parties miss out: it doesn't feel as rewarding to pay, and it doesn't feel as rewarding to have your meal paid for because it seems low effort. People almost view that as bragging vs sharing because of that lack of dance. Which is part of the illusion! High effort v low effort.

A safe way to treat people is to allow them the ability to "counter-offer". Dance with them a little, alternatively encourage them for the next event if they want. You can avoid that crude transactional feeling, plus if they are up for it, next event is their choice.
