<prompt> Human: I was involved in a motor vehicle collision a few months ago. The other driver backed into my car causing a bunch of damage and luckily he was insured State Farm. His insurance company paid for the repairs and a rental car while I waited for the repair work to be done. The rental company Hertz required a 150 deposit for the rental car which I thought was odd. I opted for the full coverage when they offered it for 21 which I thought was a deal. Fast forward a month and Im expecting to get that 150 back and see a 21 charge for the rental insurance. As it turns out I didnt read the contract very closely and the 21 was actually 21day which added up to 340tax after all the repair work was done. Im kicking myself because there isnt a whole heck of a lot I can do at this point except point out that this is how they charge for insurance, and second that my credit card company would have covered me on the rental insurance and I didnt need it in the first place. Watch the fine print.  <response>: Insurance being per-day and not per-rental is the norm.
