Yuppie buffer

A story in the New Yorker:

“They hire someone—this has happened several times—so they don’t have to talk to me,” he went on, growing more animated and reddening with amazement. “It’s like they’re afraid of me! So they hire a guy who’s more comfortable dealing with a masculine-type person. I stand there and talk to the customer, and the customer doesn’t talk to me or look at me, he talks to the intermediary, and the intermediary talks to me. It’s the yuppie buffer.”
