Has anyone else had experience with this?

So I was at a stop light, listening to some of that rock and roll and some guy gets me attention from his shiny rimmed SUV.

He asks if I'm from around here and I reply that I am since I've gone to school here for a while.

He then proceeds to ask if I know where any adult bookstores are.

So yeah I just told him that I don't frequent those places so he then just drives off.

What should I do in the next occurrence other than laughing?
