Why do guys hit on me more when I look bad?

Anonymous
I've noticed a strange phenomenon. I -always- get hit on when I look bad (or when I feel I look bad). When I feel I look really great, I get nothing.

Today I went to the grocery store, and I looked terrible, honestly. My hair was pulled up into a crappy, un-smooth bun. I was wearing a tank, sports bra, and shorts. And I was wearing my glasses. The guy at the register KEPT hitting on me. Like "Where are you from?" "Where do you go to school?" "Here's a discount..."

The above scenario has happened to me a lot. But never when I actually look polished/good.

Why?
