Terrible service from Dollar. After waiting in line to reach the counter, the man initially greeted us with a smile but then spent about three minutes adjusting his watch before asking for our rental documents. He claimed we hadn't purchased any of the insurance options, even though I bought all the insurances on Zuzuche. I checked my order and confirmed we had them. When I called Zuzuche customer service, they confirmed I had purchased all the insurances. The man then tried to up-sell us a larger car for an extra $10 per day, which we declined. He insisted we prepay $67 for refueling, saying we should return the car with an empty tank, even though a full tank of gas for the Nissan we rented costs only $27. He then asked for a $75 deposit and demanded my signature, saying I could talk to the manager afterward because many people were waiting in line behind us. With no other option, I signed and spoke to the manager, who was the first person I saw. The manager promised to refund the deposit. When returning the car 15 hours earlier than planned, I asked the manager if I could get a refund for the unused time, but was told it was not possible. I had read online reviews about Dollar's poor service and aggressive charges, but experiencing it firsthand was worse than I imagined. I will never rent from Dollar again.
