       Patricia asked for the cheapest car available at Acme Car Rental. She needed a car for 48

hours. Because it was the weekend,there was only one car available at the moment-an SUV.

Patricia was an environmentalist. SUVs,which are big cars consuming a lot of gasoline,offended

her greatly.

       But she needed something to get to Baker,a town that was 100 miles from the small airport.

So she went, RentMe instead. "I need a car for 48 hours," she said," and I don't want an SUV.

I want something cheap. "They told her they had just the vehicle for her,a 1998Toyota. Thirty

dollars a day,including insurance and other incidental fees. All she had to do was to pay forher

own gasoline. Patricia was very pleased. Thirty dollars a day was a good rate even for a weekday.

She signed all the paperwork,and they gave her the keys.

        The Toyota was a 4-speed,4-cylinder,2-door beauty,the paint,tires,and the interior were like

the new. It was comfortable, even though the air-conditioner was not the frostiest(结霜的) . She

got in and drove north. It was a two-lane road all the way to Baker,with only one town between

the airport and Baker. That town was Noms,40 miles from Baker.

        Patricia didn't make it to Norris. The car refused to run 30 minutes after she had been driving

it. Fortunately,her cell phone was able to connect back to the RentMe desk. "My car stopped

running. and I'm out here in the middle of nowhere in the hot sun! " she said.

       "That doesn't make any sense," said the clerk."You did put gas in the car before you left town,

didn't you? "

        "No. Of course not ! "  yelled Patricia. " Why would Iput gas in the car before I even got out

of town?" "Well,why do you think you got such a good

rate-we save money by having the customer gas up instead of us having to put gas in the car. "

       "I was in a hurry,"said Patricia.

       "Well,sometimes you pay a price for being in a hurry," said the clerk. " We'II send a man out

with some spare gas for you:if you'd like. ,,"

       Of course l'd like , " said Patria.ia. " How long willit be?"

       The clerk told her it would be within the hour. He didn't tell her that there would be a  $ 50

service charge for delivering the gas,or that the 3 gallons of fuel would cost her $ 7 a gallon. She

would get that bad news when she retumed the car to the airport.
