At the time of pickup, I clearly stated I didn't need any additional insurance and asked what the $137 was for. The clerk said it was a deposit that could be refunded. Since previous rentals involved prepayments, I didn't pay much attention. However, when I was charged, it turned out to be an expense, not a common $200 prepayment. I later discovered the bill included road assistance and some highway insurance, which were abbreviated and hard to understand.
