Getting A Red Flag Here

(Less than a week ago my store had a new till opening system installed. After years of cashiers having to call out to customers which tills were opening, we now have a panel of buttons to press that makes the opening till’s number light up green instead of red. This is accompanied by an overly-polite automated message for customers over a P.A. system.)

Customer: *gesturing to the green, lit-up till number at the end of his transaction* “This is all very modern isn’t it?”

(I agree and say how it’ll hopefully make things a bit easier for the customers when we’re opening and closing tills.)

Customer: “So what does it mean then? Red and green?”

Me: *deadpan* “Red means closed and green means open.”

Customer: “Oh, right. Thank you.” *walks away from till to leave store*

Colleague On Till Behind Mine: “I REALLY hope he didn’t drive here today!”
