Another Way They Make You Cry, Part 2

(I am allergic to red onion and if I come into contact with it at all start having typical allergy symptoms (runny eyes and nose, itchy throat, etc.) but after a few hours I actually have trouble breathing. I am always careful to check ingredients before ordering and whilst cross-contamination can sometimes occur, it does not happen too often. I am ordering a kebab and have asked for meat, sauce, lettuce and tomato. This shop uses red onion.)

Shop Owner: “You don’t want any onion?”

Me: “No, thanks, I’m allergic”

Shop Owner: “Yes, but they’re very good for you.”

Me: “Thanks, but so is breathing.”
