It really doesn't sound good. A loss leader is meant to get you into the store; the gas station is usually far away, in the back of the parking lot.

Their $5 chicken now, that's a great "loss leader" (if it even is; that isn't confirmed). Because that forces you not just into the store, but all the way to the back. So you go in for the $5 chicken and leave with $20 of blueberries, $20 of cereal $20 of milk $20 of mayo.
