OCD About Fakes

(I have OCD, and I have a habit of folding whatever notes I have in my hands in half, then in half again. The manager who is serving me is taking so long that I have already done this by the time I pay.)

Manager: *taking the note and looking at it* “This is fake.”

Me: “Really?”

Manager: “Why else would you fold it like this?”

Me: “OCD?”

Manager: *scoffing* “Sure. Try a better excuse next time. Got any real money?”

(He handed the note back, which I promptly unfolded and returned to him. He stared at it suspiciously, before getting a verification pen and practically colouring the entire note in before finally accepting it was real. He refused to speak to me after that, and walked off before I could even say, “Thank you,” when he handed me my receipt.)
