Oh, and I wouldn't bother getting him more food tomorrow - just wait until your next scheduled feeding, and he'll be all the more happy to take his first adult mouse.
^^ That. Also, I wouldn't worry too much about not feeding for a week. Even 5-month olds can go a couple weeks without losing any weight. I'm kind of sympathetic to the store on this one since sometimes we run out of a size at my work and I'm on the receiving end of this kind of anger. Your snake will forgive you, I promise.
