If you walk back in and confront the bastard

You stalk back into the store holding the bread by the twisty end handle like it's a nunchaku. Hasterson goes pale when he sees you. You walk slowly forwards like a gunslinger of old.."I'm calling you out Sigall Hasterson". You step up closer and flick out the bread sack, it strikes the bastard upside the head, driving him to the ground, racking his face against the register on the way down.
