The ignorance shown towards people on crutches, especially in supermarkets. The wife is recovering from a knee op, and we went to Asda yesterday, and amount of idiots blocking our pathway in aisles was unreal. They'd see her hobbling along but wouldn't move till asked, or would tut or grumble when asked to move. The car park was just as bad, impatient folk nearly knocking her down because they are in so much of a fucking hurry to go shopping.
