This exact scenario sounds threatening and like a total buzz kill. You need to understand that being out in a bar situation is a little vulnerable for women for obvious reasons, how am I supposed to know the guy coming up yelling to do a thing is safe? This could turn scary so dang quick. I get that you are just trying to be friendly and personable, but if I don't know you then I would absolutely be taking a step back and wish you hasn't done that.

I can't speak for all women, but you asked. I'm not even remotely suprsied that this isn't something other women don't reciprocate. I think maybe you should reconsider doing this.
