Avoid Thrifty/Dollar at all costs !!!!
After waiting in line for over half an hour to pick up my reserved rental car. I was asked if I wanted their insurance to which I replied no. But then I neglected to scrutinize my receipts and I didn't realize they had charged me for the insurance until I was home in California. Thrifty/Dollar Will not reverse the charge. And my credit card company wasn't much help either because the charge was on the receipt. But I will avoid them like the plague in the future.
