At the airport counter in Spain, a lady was very cold. I consider myself good at English with strong comprehension skills, but when I told her I wouldn't buy extra insurance, she completely changed her attitude and ignored everything I said. In the end, another male colleague took over, he was very nice and clearly listed all the costs. However, we still had to pay extra for insurance and other charges, totaling over 100 euros, which is more than double the rental fee!
