My mate Jordan, rest in peace you mad bartard, used to me physically sick at the sight of condiments.
He was being particularly obnoxious one afternoon, pissed up hanging out my car window hollering at people. I stopped to get him some food to shut him up. Came back with a bacon buttie for the two of us.
My butty had ketchup in it. Said "Oi Jordan, I think this is yours" and opened my butty up in his face. He just started hoying up out the car window, calling me c… for abusing his phobia.
Got him to behave though.
I have vague memories of drawing an outline of ketchup and brown sauce around him when he passed out one night, like a chalk outline.
