Fuel Delivery problems of the 1999 Plymouth Grand Voyager

Fuel line in engine compartment was spraying fuel where the flex line connects to the solid line that feeds fuel to the injectors. As luck would have theres was no fire only a bad smell in the passenger compartment. I was charged by the dealer to repair this leak, which amounted to putting a new clamp on the fuel line. The service man made the comment that the original clamp was to large and he installed a smaller one. Should I have been charged for this repair of "fix" ??.
