I just spent a pleasant hour at ASDA. It's sad to be so pleased by something so commonplace, I know. But I don't own a car, and a trip to ASDA on foot takes up quite a chunk of an afternoon. Anyway, they had everything I wanted, unlike my poorly-stocked local Tesco, and the customer service was excellent (also unlike my poorly-stocked local Tesco). I got a refund for some really disgusting own-brand chocolate spread and a double refund for some really disgusting own-brand low-fat peanut butter because it was on a special trial (give that one a miss: three times as much sugar as in regular peanut butter, and you can certainly taste it!). A fortuitous twist was that the refund money gave me a pound to put in the trolley before I started shopping. I'd neglected to bring any change with me because I always forget they keep their trolleys chained up.
