I agree, however that nutter tends to be in the supermarket these days on a scooter. It happened in the supermarket last week.If you have a small child the last thing you want is to have to trek across a dangerous carpark with them, especially if you have shopping or a trolley to carry as well. You don't want to risk getting run over by some nutter who can't see a small person by your side.
On a serious note, nobody is saying that we should do away with blue badges.( just have a witch hunt) We just want it policed better,unfortunately not everyone is honest, and the system is abused. I am sure the people who have blue badges on here would not like to see people parking in the disabled bays dishonestly.
