They Would Have Figured It Out… In Ten Minutes

(I work the customer service booth in a large mall.)

Customer: “I wanted to go to [Store in the mall], but they’re closed right now.”

Me: “Really? That’s odd. The mall is open right now; they should be open.”

Customer: “Yes, they had a sign on their door that said, ‘Back in ten minutes,’ and I have no idea how long it’ll be before they’re back. Do you know when they’ll be back?”

Me: “Um… Probably about ten minutes, I would think.”

Customer: “Oh, okay! Thanks so much for your help. I’ll be back then.” *walks away*
