He used to work in car rentals. His boss told him "the best retort" to use when someone comes in just asking for a price. (The price varies depending on place, time, and car.)
"How much to rent a car?"
"I'd be happy to tell you - what's the city and the date?"
"Hey, I just want a price."
"OK. A million dollars."
"Well, if you give me a date and city we might be able to get something cheaper."
:-p Hard business, working with people.
