No offense but that's the lamest excuse that i've ever heard. What are you doing, asking out 5 year olds? But since we're speculating what could happen and not what actually does, in theory if you asked out one of these girls she could say yes because she wants to drag you in an alley and take your wallet, but not after calling her friends and talking about what a loser you are after you showed positive interest in her.
I'm not saying that doesn't happen, but it probably will. She might even be the local news anchor's daughter in which case she'll announce it on tv how much of a pervert you are for asking her out for coffee. Everyone knows coffee drinkers are the worst kinds of perverts. Hey, I'm not saying it happens all the time but its very likely to happen to you. So dont take your chances because there aren't many lonely women out there waiting to be asked out, and you wont regret it when you're 70 years old in a rocking chair with just a dog wishing you didn't waste your time being cowardly when you were young and beautiful.-
