I don't shop at Sainsburys but if I did this might persuade me to stop

I don't shop at Sainsburys but the news that they are to use motorbike-riding traffic wardens to patrol its car-parks and fine customers £50 if they misuse the disabled and parent and child parking spaces would be a factor in deciding me to shop elsewhere if I did. That and their alcohol sales policies speak of a Supermarket who wouldn't want the custom of a childless, able-bodied customer, preferring those with children. Fine I will continue to take my above average weekly shopping budget elsewhere.
