I got stuck last week in a snowstorm and wasn't charged. I think it depends on the conditions.
I mean, come on! We're out there in blizzards delivering our customer's packages and we get stuck trying to make service on our customer's packages and now its the driver's fault he (or she) got stuck on a street with a foot of snow on it?
If that's not an injustice, than I don't know what is. Please explain a greater one.
