Assault By Battery

(I am in the middle of helping a customer find a picture light to hang above her painting.)

Me: “Were you looking to power it by batteries, plug it in, or hardwire it?”

Customer: “Definitely not batteries. I can’t have batteries. I’m allergic.”

Me: “You’re… allergic? To batteries?”

Customer: “Yes, one of them split open on me once, and I got a horrible rash from the stuff inside!”
