Rightly Color Blinded By Your Illiteracy

(I work at a membership store with an alarming number of people who seem to come in simply to cause a problem and then not purchase anything. I have learned what things to be oddly specific about.)

Me: “All right, please sign your name, sir. When you are finished, just tap the green button that says ‘OK’ on the bottom left corner with the pen.”

Customer: “What if I’m color-blind?”

Me: “…the button that says “OK” on the bottom left corner with the pen.”

Customer: “What if I can’t read?” *his tone starts getting angry*

Me: “Tap the button on the bottom left corner with the pen.”

Customer: “What if I don’t know my left from my right?”

Me: *having given up* “Then that is quite something, sir.”

Customer: “Whatever!” *still mad, he taps the button… with his finger*

Me: “Sir, I said with the pen…”

(He ended up being so angry about the whole thing that he left without his order, his membership card, and his wallet. I took his personal belongings to the front desk and then had to close my line to go return everything.)
