HK, that is one of the best posts I've read.
Not just here, anywhere.

Ditto.
Though I question the business card... did he give his cell #, or was it just the business phone? How about a personal card (as someone else suggested), or even a simple piece of paper?

If I didn't like the looks of the guy, or he felt creepy, I'd try to find a polite way to say 'not interested'.
(But always be ready to enforce that 'no' if it turns out there's a reason for the creepy vibe.)

And yes, lunch or coffee would be even less threatening.

No. And as others have mentioned, I return the favor.
I'm perfectly capable of opening a door for myself, & I suspect most people are. It's just a nice gesture.
