Me: “We do have seats available on that flight, but if you were willing to leave an hour later the fare would be $200 less. Would that work for you?”

Elderly Customer: “That’s not a brainer!”

Elderly Customer: “That’s what the kids say, ‘not a brainer’. I’m going to use it on my grandson to show I’m hip with the kids.”

Me: “I think ‘that’s a no-brainer’ might be more usual.”

Elderly Customer: “You know what else the kids say? Go f*** yourself!”
