(In order to proceed on our site, users need to type in a signature consisting of their name and their username, which is an eight-digit number.)

Customer: “Every time I’m typin’ in my signature, it ain’t accepting it.”

Me: “Okay, well, I just want to make sure everything’s entered correctly in our system.”

(I read out their name, including spelling. Everything’s correct.)

Me: “Alright, let’s check your user ID. It should be zero-one-six—”

Customer: “Now, hold on. Do you mean the letter zero, or the number zero?”

Me: “…The number. Zero is a number.”

Customer: “Oh…huh. Well, that may be the problem. I been usin’ the alphabet-zero this whole time!”
