So you can use LV's to buy Tequila, big deal! I heard of someone who used theirs to buy a Plasma telly. Smart thinking.
Anyhoo, to be really correct and not misuse them, one would have to go to Tesco twice a week with one trip solely for 'work related' foodstuffs (oh bugger, I've run out of butter, I'll just nip down to Tesco for a half pound rather than use what's in the fridge
). B***ocks to that, once a week at our local Tesco is enough to have me reaching for the sharp knives.
