(A customer comes with an old toolbox.)

Customer: “Hey, look what I found just outside…”

(The customer opens the metal toolbox filled with mushrooms.)

Customer: “I doubt they’re the kind that make you high.”

Me: “Um, I wouldn’t eat those. I think they’re destroying angel mushrooms, which are deadly poisonous.”

Customer: “If they are, then I’ll probably eat them!” *leaves the store and never returns*
