bimsey > Have a look at what people in a queue are like. Avoid checkout queues with : dippy staff on the till (inevitable), the elderly, mothers with small children or pushchairs, luncheon vouchers, large quantities of fruit & veg, large trolleys (obviously), and people who still insist on paying by cheque, despite the fact that their compulsory guarantee card could have been used much quicker by itself. At the end of all this, you'll avoid food shopping, and only do it online, or eat out!
