Slow people

Almost got pinned by a car in Sam's parking lot this afternoon. It just kept backing up until it was a yard away from the row of parked cars behind it then backed up some more at an angle until it was perpendicular to those cars and almost grazing their paint.
Aside from using mirrors and actually turning your head some, aren't you taught to pull out at an angle so you can go forward once you clear the parked cars?
Then when I was in Target, people didn't know how to steer their carts as to not block MAIN AISLES.
It's called the race track for a reason.
Checking out at Target is slow because the cashiers are seasonal and don't know how to approve credit card transactions.
