Let's assume you are at the bar, a coffee shop, store, etc. and a short guy approaches you. Not a lot shorter than you, maybe the same height or at the very least only a couple inches shorter. Assume, he's not creepy or ugly, just your average guy. He's also got no problem talking to you, as in his "game" is decent.
How would you react? Would you immediately discredit him because he is shorter than you or would you hear out him and give him a chance to see what he's like? Would you even bother talking to him, or would you reject him on the spot? Would you talk to him just to be nice but reject him if he tried to take it further like ask for you number?
