Bars in Asia

So I've noticed this trend that people in Asia don't eat or drink alone at the bar. Currently, the Japanese bartender at my hotel thinks I am a total dingbat. I am sitting alone at the bar and I've ordered OMG 2 glasses of wine by myself. The look of utter bewilderment and disgust was priceless and a bit off putting. Yes, I am a foreigner and blond and a woman and I drink alone if I'm traveling alone. I don't want to sit alone in my room and work...I do that almost every night. I know culturally it's different...eating and drinking is relationship development or guanxi in Chinese. It's a social occasion. So a rather odd/random question, how does one pick up someone at the bar in Asia if everyone is in a group? Food for thought...not for me though! In T minus 17 days I'll be with my sweetheart in Bali! Yay! Like the pics?! I can't wait!
