Not sure, but would guess that it's to work better with road-placement, since the fast-feeder has a drive-thru and the roads might not always cooperate with one particular layout

Ideally the bar's parking would be in front of it rather than behind, for those times when there's no easy/not-offroad way to get at the rear of the building.  Same general idea as the road-based fast feeder, and implemented with the gym, dojo, etc.
