This Is Spin Cycling Out Of Control

I’m installing a new washing machine into a home. The customer did not purchase a new hose.

Me: “As per company policy, we can’t install the washing machine without new hoses, but you can just screw in your old ones, and you shouldn’t have a problem.”

Customer: “The hose just connects into the back here?”

Me: “Yes, just like a garden hose.”

Everything is perfectly fine at this point. But then the customer picks up the washing machine’s plug that is literally just a regular plug in that you plug into an electrical socket.

Customer: *Eyes widen, visibly angry.* “Okay, this is getting too complicated! Send it back! I’m never shopping at your shop ever again!”

I tried one more time to show him where the hose went, but he wasn’t having any of it, and we were forced to take the washing machine all the way back to the warehouse.
