A man's car runs out of gasoline. His car tank holds exactly 13 gallons. He has three empty unmarked containers which can hold 3 gallons, 6 gallons, and 11 gallons. Using only these containers at the gas station, how can the man bring back exactly 13 gallons?

(He is not allowed to buy over 13 gallons and dispose of the extra.)

First fill the 11 gallon container. Then use the meter on the gas pump to fill 2 gallons on one of the other containers.

Honestly, when was the last time you saw a gas station that didn't have meters on the pumps? This gas station owner needs to get with the times!
