When my Dad used a wheelchair,id take him to the local Tesco,one day we couldnt park in the disabled bay,as some muppet had parked there,so had to park further away.
When we came out the disabled bay was empty,so i left my dad at the entrance,with our trolley of food and christms gifts,and went to get the van, reversed into bay.
Within seconds a chap drove right up,flashing lights,and horn going,screaming thats for disabled only,i just ignored him,he jumped out of the car,and started screaming again,by this time the security staff had come out and we had a crowd,he shouted at the everyone i was parked in a disabled bay.
The security chaps decided they had better earn their pay and said to me,Sir thats a disabled bay,for use by disabled badge holders only.
At this point i pointed to my father,and said thats my dad,hes blind, got terminal cancer,and cant walk,how disabled do you want him to be.
Everyone went quiet,i just turned round to the angry man and just said Now **** off and get a life.
