if you were going to murder someone in tescos, i advise you to do it by the jars of beetroot, as no one will be bothered by the pool of blood. especially if you do it at my local tesco where it's more of a novelty to find a clean bit of floor. in fact, they'd probably scoop up the body and put it in the reduced goods area and sell it off cheap.
not that funkypancake in any way condones or encourages murdering, either in supermarkets, or outside them (or even in the entrance)
