Narrative:

While on the ground at the jet center, I watched the fuel boy top off both tanks. I checked for water and then went for takeoff. As soon as airborne, the left wing fuel cap came off and, coming back to land, we lost 17 gals of fuel. I showed the fuel boy who was waiting how it happened, but they denied any responsibility.
