That?s all OK if people want to buy a few items that they can carry, anything more won?t be possible. In turn making the ease of large supermarkets like Sainsbury?s far more appealing. I also don?t see how a 30 minute window is helpful for anyone wanting to do their shopping...it would definitely stop them from using one of the local cafes or restaurants. This is very concerning and has been the death of many high streets...let?s not let ours be next!
