I was wondering much the same thing myself. I stayed in lane and let my foot rest easy on the accelerator, trying to remember what the ecology commercials were always telling me about ways to conserve gasoline. No fast starts, no jamming on the brakes, and don’t spend too much time warming up on cold mornings. Sound advice, all of it, but I couldn’t see how it applied, and I clutched the steering wheel and waited for the engine to cut out and the world to cave in.

Neither of these things happened. I found a Chevron station a block from the bridge and told the attendant to fill the tank. The car was a sprawling old Pontiac with an engine that never heard about fuel crises, and I sat there and watched it drink twenty-two gallons of high-test. I wondered what the tank’s capacity might be. Twenty gallons, I decided, figuring the pumps were crooked. It’s a dog-eat-dog world out there.

The tab came to fifteen dollars and change. I gave the kid a twenty and he gave me a smile in return and pointed to a sign on a pillar between the two pumps. You had to have exact change or a credit card after 8 P.M. Help us thwart crime, the sign urged. I don’t know that they were thwarting anything, but they were certainly taking the profit out of it.

I have a couple of credit cards. I’ve even opened doors with them, although it’s not the cinch TV shows might lead you to believe. But I didn’t want a record of my presence in Queens, nor did I want anyone copying down the Pontiac ’s license number. So I let the little snot keep the change, which got me a mean grin, and I drove east on Queens Boulevard mumbling to myself.

It wasn’t the money. What really troubled me was that I’d been driving around unwittingly with an empty tank. The thing is, I don’t steal cars very often. I don’t even drive them all that frequently, and when I do go and rent one for a weekend in the country, the Olins people give it to me with the tank full. I can be halfway to Vermont before I even have to think about gasoline.
