Their Dine And Dash Hopes Were Dashed

Me: “Hi, welcome to [Restaurant]!”

Customer: “Hi. I am paying for four, with drinks.”

Me: “Okay. Your total is [total].”

(As the customer pays, her three friends come in, walk past her and sit at a table across from the buffet and whisper among themselves. The woman that paid gets her food, then her friends do, too. After about 20 minutes I look over at their table and see the three friends whispering again and looking at me. Suddenly the three of them get up and run out the exit door laughing. Once they get outside they high-five each other and look back at me and my coworkers, taunting us.)

Customer: *to her friends* “I paid for you already!”
