So last Friday some dude I passed on the sidewalk randomly stopped me

and asked if I wanted to have coffee or lunch sometime. Yeah, yeah, I'm just *that* compelling.
But no, seriously, people do this?! Dudes, have you ever done this to a broad? Chicks, has a dude ever done this to you, and how did you respond?
I had a friendly conversation with this dude but said there was no way I was giving a stranger my contact information.
