Extra Register Does Not Register

(A coworker and I are working the registers during an early afternoon shift at our store. We are both busy ringing out customers at our respective registers, when an elderly gentleman, looking highly confused, approaches my coworker with two younger girls. Keep in mind that I am currently handing my customer her change for the transaction and her receipt, and my coworker is scanning items for her customer. There is also a sign above the registers that says “Check Out Here.” This is all in plain view of the elderly man.)

Elderly Customer: “Is this a register?”

Younger Girls: “YES, IT IS A REGISTER!”

Elderly Customer: “Are you sure?”

Coworker: “Yes, sir, this is a register. Either I or [My Name] could help ring you out in one moment.”

Elderly Customer: “But are you sure? All you are doing is folding clothes. Can you ring me out here?”

Coworker: “Yes, sir, I can ring you out now.”

Elderly Customer: “But you can ring me out here?”

Coworker: *clearly getting annoyed* “Yes, I am free to help ring you out right HERE.”

Elderly Customer: “Okay, but this is really a register? You looked busy folding those clothes, I assumed you were putting them away. I’m so happy you can accommodate me and ring me out here. It would be too hard finding the actual registers!”

(All the while, one of our supervisors overhears the conversation and walks over to me.)

Supervisor: *whispers* “Because clearly the area marked ‘Check Out Here’ is not a register! We should have told him these were the dressing rooms!”
