I was up at the supermarket earlier and a huge row was going on outside the supermarket. Apparently a mother with two small kids was furious that someone without children had taken the last P&C space and had just blocked him in and gone off to do her shopping. As a result she was causing a huge obstruction for other customers trying to drive up to the exit and was also impeding the view of other cars trying to reverse out of their spaces.
AIBU to feel that she was taking the situation waaay too seriously and should have just gone off and parked somewhere else.
