I also like to walk around bars. Not to get drink or "hang out", as it is customary for many people, but to look for unusual tastes, try interesting drinks, listen to the atmosphere of the place, look at people. Each bar has its own soul, and I like it.
Turn offs:
At the same time, I really appreciate personal space. I don't like familiarity, when a person forgets that he has another person with his own boundaries. Disrespect and tactlessness immediately put barriers, and I'm not on the way with such people.
