When you see a guy with a hot girl do you assume "she's after his money"?

I've always wondered this. I've asked some of my girl friends before and they say yes, but I just personaly don't think like that. I will see a couple and think "they both are nice looking" or "he's ugly but she's pretty" or whatever. I really don't think too much about it. I think people who think like that are just jealous they aren't out there hooking up with people they think are hot.
