Avis Rent a Car
Endangers single women in the dark

Avis requires that receipts be presented when cars are returned, showing that the gas tank was filled within five miles from the return location.
Returning a car from a distance of more than five miles away at 5:30 a.m. in a strange city where gas station locations and hours are not known means driving around hoping to be safe, finding an open station, and finding the way back to the airport car rental location.
