Car Wash<br>When I bought gas I bought a car wash too. After pumping the gas I drove over to the car wash. My car was really dirty. The car wash did a wonderful job. Now my car is sparkly clean again.
When I bought gas, it came with a free car wash. 
It is stated that the car wash was purchased at the same time as the gas.
