In 2012 in Boston, Enterprise refused to deal with my (European) debit card. However, in general this is right: US standards of customer service are unreachable anywhere in the world, except probably Japan. To the US people expectations, customer service is simply nonexistent here. "And remember -- here in France, the customer is always _wrong_!"
They placed a $1 hold on the card. If memory serves, I've also done this with Hertz but to the tune of a $200 hold.
