(I work at a video store, where in order to rent movies we ask for a phone number and then read out their name to verify the account. You can have one primary account name, with others added on to it. This particular customer was on the account under his wife.)
Me: “Phone number, please.”
Customer: *reads out number*
Me: “Are you under [name of wife]“?
Customer: “Not tonight. She’s mad at me!”
