It didn't occur to me before I sold him the animal, he assured me it would be fine. Now I'm stuck between a rock and a hard place. I sold him this snake, I should have known better about the motorcycle and refused sale, but this was my first purchase to someone buying with a bike, and he drove a long way for it.
He has requested a refund at some point. I can either refund for something not really my fault, and keep the possibility of a future customer, or tell him it's his fault the animal died. Anyone ever have a situation like this, it's a first for me.
