Rick runs his hand through his hair. Damn kids. He puts a ten on the counter, sliding it over towards the girl.

"Guy by the name of Desmond. Med student. Good looking. Know anyone like that? Know where he might be hanging out, that sort of thing?' Failing that, you know where the med students have classes?"

I don't believe Rick ever received a physical description of Desmond, but if he did, he'd tell the girl that as well.
