There's also a random chance that the Rob mission will just fail. I
think it's something like 1% by default (probably depends on server?),
which means there is always a small chance that you will try to rob
and just get nothing. (I found "RobFailureOdds=1" in the PCONFIG.SRC
file for the game I'm currently playing, so you should be able to
check what the failure rate is.)
So if you want to be extra sure, you'll need extra ships helping rob,
in case one fails.
>> Stay informed about: zero fuel ships
