John, Party Of Noooo

(I work as a hostess in a popular steakhouse. On this particular night, we are busy and have a wait and my general manager is running the desk. Our hostess desk is right by the bar, which can be very loud.)

Manager: “Good evening! Welcome to [Restaurant]. We are on a 30- to 45-minute wait currently. Can I get your name and number in your party?”

Customer: “John for two.”

Manager: “Great. Can I get a last name?”

Customer: “No, just John.”

Manager: “Sir, we have a long list here and it would be easier if I had a last name.”

Customer: “No, just John.”

Manager: “John is a very common name; I wouldn’t want someone else to take your place because their name is John also.”

Customer: “I CAN’T BELIEVE YOU!”

Manager: *pauses* “Sir, may I have a last name to ensure we have the right party coming up when your table is ready?”

Customer: “I CAN’T BELIEVE YOU!”

Manager: “Okay, then John, party of two.”

(When the name John was called, no one came up.)
