After rebuilding the CX on the bow of our boat, we had problems with the fuel tank rusting from the inside. So we stopped at a fuel station to flush it out. When the tank was empty, and all the gasoline flushed away with the rust, we took the empty tank to be filled. Inside a concrete bunker, the cash desk was staffed by a woman who had been watching us the whole time. Even though she had seen us throw away all our fuel, she never told us the gas station was empty and not expecting deliveries for a month.
