I know why our local Tesco has block paving between the trolly park and the store entrance; it's so you don't realise you have a trolly with square wheels until you are in the store and can't be bothered to go back and change it (probably for one that was made for a roundabout). C'mon Tesco, you make a hideous amount of profit (every penny counts, it does for Tesco) the least you can do is let us give you our money with out the threat of maiming a little old lady with one of your wonky trollies. over 2 years ago via web
