Overall, I wouldn't think twice about it. If you are a good customer, then you will be welcomed with open arms. An owner of a bar is not a thin-skinned. You could simply say the next time you go "Kono mae, sumimasen," meaning "Sorry about the last time [we were here]." I think you are overthinking it. There is no reason for you to lose your sanctuary because of the actions of someone else, your guest or not.

I used to work at a bar in Japan, and some of our "best" customers were awful.
