It made sense now: sold vehicles probably passed through that route to refuel with a few liters before being handed off to their new owners, ensuring they had enough gas to reach the nearest station before the new owners drove away with their newly purchased cars.
This also meant that once someone was sent out to pump the gas, Fred and Rose could cover them, keeping watch and protecting them while they drained as much fuel as possible from the shared storage system. The main fuel reservoir was probably located elsewhere, but they didn't have a scout available to search for it. Not that it mattered much — they could still empty the shared supply by siphoning fuel from the dock positioned near the exit.
Fred and Rose continued fighting for a few more minutes before hearing movement behind the door — the rattle of a doorknob turning. Fred turned just as Reeve peeked out through the narrow opening.
