At dinner, Mom's food came out cold.

Manager:I'm so sorry. Anything I can do? I feel so bad.
Mom:No, it's okay, really. It happens.
Manager:Okay, I'll take 50% off the bill and give you a coupon for next time. How about dessert?
Mom:No, it's alright -- not really feeling dessert tonight.
Manager:What about to take home?
Mom:Oh, I'll take a brownie to go.
--- The manager leaves.
Mom (to Dad):Okay, here's the deal. Next time -- *your* food comes out cold.
