Welll you just dont walk straing in. You first exchange glances, see if shes alone, whatt shes drinking (soft drinks, hard licor, beer, some fancy cocktail) and judge something about her personality, if you think you have a chance, then you pay for a drink, or just straigth hit her with something, in my case somthing dumb like "Hey, how much a polar bear weigths? Enougth to break the ice!".
What I think is creep is some stranger who straigup knows your name, your face, and can just as easy starting to virtual stalking your life and find out where you live.
Fucking hating online dating solutions like tinder.... really not good talker on line, without seeing the person face to face.
