There's a few parts of that anecdote which confuse me as a pilot. The first one is two vastly different aircraft separated by a slash as if to indicate that they are equivalent. The second is an air crew that completed a flight, while leaking fuel, without declaring emergency and putting it down. Lastly, someone actually observing fuel leaking from the aircraft and thinking "meh, it's just old," rather than alerting the air crew. (Put another way, I have doubts that you were observing a fuel leak. Those are generally pretty easy to notice -- "why are we consuming two thousand extra pounds of fuel per hour?")
