I do not think it would get much traction in bars of, for example, U.S.A. Maybe caffes would be a better choice. There are places called "bars" in their localities around the world where the atmosphere may be a little different from what I have seen in the U.S.A. I have been to such a place named Vinyl and one named Hi-Fi or something along those lines. (I am almost, but not entirely, certain about that name). Both focused on serving drinks and whatever else in a heavily audio-themed environment. I doubt any patron went to the store, literally accross the street, and bought new equipment.
I used to go to a place, neither of those two mentioned above, where owner installed very decent system. Higher level Bowers and Wilkins speakers in all the rooms, whatever was "finer than what you expect in a caffe/bar" electronics, etc. He told me he spent so much time at work that he did it for himself so he could listen to finer sounds. Not for the crowd. Once the place filled up, you could not hear yourself thinking, much less nuances of mids or bass.
