Should Have Heard It Through The Grapevine

I work at a winery. A customer has wandered into the tasting room. He’s been rude and brusque to the reception staff (and possibly a little sexist).

Customer: “So where do you grow your grapes?”

I turn around and look through our enormous balcony windows that overlook our vineyard.

Me: “You see those two hundred meters of vineyards that you had to drive through to get to this tasting room? There.”

He was less talkative after that.
