College student here: See a lot of hot college girls walking around in grocery stores. I figure I'm a decent looking guy I probably could pull it off with girls my age (especially if she goes to my university)...

But I've never tried it before, I'm not really even that great at this kind of thing anyway, but the grocery store is a casual environment and I may be good at it.

What's your opinion on the idea? Any advice? Should I expect a higher than normal rejection rate?
