Waitress: "Can I get you a drink?"
Patron: "No thanks, I'm good."
Waitress: "No offense, sir, but there's a 2-drink minimum here."
Patron: "Duly noted. I don't need a drink."
Waitress: "Um, is there a reason why you're not drinking?"
Patron: "Yes, miss, see those two schleps sleeping at the bar? They're hoping to get lucky once you return from the kitchen, and ask them if they need a ride home."
Waitress: "Ew. Those two?"
Patron: "Yup."
Waitress: "But you're not drinking?"
Patron: "Yup. Actually, I'm the designated driver, and those two are obviously my drinking buddies when they need a ride."
Waitress: "I'm sorry I bothered you."
Patron: "You know, there is something you could do. What do you say we ditch those two schleps, and I take you out for coffee once your shift ends?"
Waitress: "What about those two schleps?"
Patron: "They'll still be here after I take you home. I can pick them up on my way home."
Waitress: "You're a good friend. Yeah, I'll take you up on that coffee."
Patron: "You can take my dinner plate, and I'll take care of my tab."
Waitress: "See you in a few minutes."
The Two Schleps: Gives Patron a thumbs up.
Patron: Walks over to the schleps. "Same time as last time, guys?"
Schleps: "Yeah, bro, thanks for driving tonight."
Patron: "I love you guys. You're the greatest wingmen known to mankind."
