OT renting a car.

A friend just came back from Florida where she rented a car but took
none of the extras offerred.

The rental guy tried to sell her INSURANCE but she said she was
covered by her own insurance, but he said not for LOSS OF USE. What
does that mean, she can't use the rental car! Don't they just give
you another one if you break the first one?

He also wanted to sell her a full tank of gas so that she didn't have
to fill the tank at a gas station before she returned the car. She
took that to mean a FULL tank of gas even if she was only half empty.
They were charging 3.05 a gallon and she filled up near the air port
for 2.93, I think, or 12 cents a gallon difference, so if they were
only going to charge her for half a tank that would have only been
maybe $1.20, which she would have gladly paid. But he called it a
FULL tank of gas. Also, do they ever lie about how much they put in?
Since the customer doesn't see the pump.
