Well, in all fairness, if I understand the movements correctly, Macaroni and Chobi aren't even heading towards that supply base, they're moving to the RV with the rest of the support team.
Besides, it seemed like a good idea at the time.
That said, I do think Latrova would be quite pissed on the loss of fuel, particularly as Zhar ought to be running low by the time they get there...
