It does not reset your sobriety because the intention wasn't there.. it wasn't a relapse!
I would have had a few choice words for the bartender. I am glad, if the manager was sincere, that the staff might get more training on this topic. Good for you, for approaching him about it, you did the right thing. And I am really glad to hear that being immersed in that culture is not a trigger but rather reinforces your values. That's so awesome.
