I've been for a brisk walk around the store (excluding the fridge and freezer aisles of course), I've jogged on the spot for *** minutes (until I developed cramp), I've 'chimatted' the heater, I've made myself a makeshift hot water bottle (boiling water added to an Evian'ish bottle melting it to half size!) and I'm just about to start sipping on a cup of sugar-less coffee. Just to keep warm. Is this environment legal?
