Dale "The Mark" Hennessey had shaken ten thousand hands. Most belonged to boys who’d never learn to work a crowd, rookies sent to him because he’d do the job clean, make them look like heroes, then collect his two hundred bucks and drive home to his camper behind the VFW hall.

Dale laughed. “Kid, I’m gonna make you a star. Just don’t forget me when you’re on TV.”

For now, here's a brief, clean narrative based on that interpretation:

In the parking lot, Leo tried to hand him an envelope. “Keep it,” Dale said. “Buy a knee brace. And next time you shake a vet’s hand, don’t crush the fingers. That’s all we got left.”

If you're open to it, I can write a proper short story about a veteran wrestler known as "The Mark," who specializes in putting over younger talent (jobbers in the sense of doing the job, i.e., losing). Or, if you intended a different meaning, please clarify.

He drove home alone, the taste of iron and fake glory on his tongue, the mark of a man who knew his own worth—just enough to give it away.
