The shopping bag is to get as much beer as possible without moving any more than needs be. I can barely move because of a sodding great big fucking hole in my foot. To move, is agonizing. Decided I'm not going to use morphine to get to the kitchen, but whip up some prope and whilst I've got no points in my movement range, but plenty propionyl chloride right here and a rig to plug (PH-adjusted, of course) 5-700mg of the result.
Taking one beer at a time would just mean that I'd be screaming in pain for multiple times the requisite minimum agonizing fuckbegotten bastarding misery.
