Tennis anyone?

I was doing my photography (as one of my job titles is newspaper ad photographer) and one of our salesmen walks by and says:

You like to play tennis?

Tennis??

Yeah, tennis.

Uh, I guess so.

And then he just keeps walking. It was so random. I mean, it's not like I was carrying around a racket and tennis balls. I wasn't wearing a tennis outfit. No tennis shoes. Nothing that would even remotely hint towards whether or not I'd ever play tennis. Is it because I'm white? If I was black would he have asked me if I liked to play basketball?

He's lucky I didn't ask him if he likes to swim across the Rio Grande.
