Do people really ever become friends by chatting over a cup of coffee?

@LifeIsShort So you're walking down the street. A chap, who hitherto has been a complete stranger, strikes your fancy. You approach him amiably and no doubt hesitantly and inquire, "Care to have a cup of coffee with me at the nearby Starbucks? Perhaps our verbal exchange over coffee will, in time, turn into a lifelong friendship." Won't he think you're a tad odd for making the entreaty? How will that ever work out well?

@flipper1966 It would be more than just a tadd odd if I did that.

@LifeIsShort Because you wear a Russian army uniform?
