Overcoming the initial pressure to drink everytime to interact with new people at a bar might be feasible if you are allistic. That sounds exhausting to me.

And if you think that even generally good people wont subconciously place you in a different category as a non-drinker (or even someone who stops after a certain number of drinks in my case) I feel that is a naivety.

Further, even among less good people, you might want to care. There are material consequences to one's social standing. They just aren't immediately obvious.
