Thrifty counter staff experience very poor.

I have rented cars from Thrifty through Easyrentcars.com twice this year: on both occasions I purchased the Super Insurance Package when making my booking online. When collecting my car on both occasion, the counter staff attempted to sell me LDW Additional insurance. When I explained that I had already purchased additional insurance and that LDW insurance was included in my total rate, they became very persistent in their efforts to convince me that I was underinsured and that I needed to purchase more insurance. On the first occasion the Thrifty representative became quite rude when I continued to refuse to be persuaded to buy insurance that i had already purchased. On the second occasion the Thrifty representative spent a considerable amount of time telling me that I did not understand the situation and that I would be breaking the law by driving the vehicle without first purchasing insurance from him: he kept me waiting at the desk to collect my car for almost 45 minutes although I had all the required documents including proof of all the insurances I had purchased. On both occasions i found the manner of the counter staff rude and intimidating, leaving me a very negative perception of the Thrifty Car Rental experience.
