I have stated at least half a dozen times in these threads what I learned from RPA's interaction with Amtrak about how revenue is allocated to the F&B account for complementary Sleeper meals, and before me AlanB had stated the same based on information from his different source within Amtrak. But that appears to be unacceptable and people keep going on and on asking the same question over and over again. That is why I don't bother answering it over and over again. I am happy to let people believe whatever they wish to.
One more time ... a fund transfer equal to the food check amount in the dining car is transferred to the F&B account. I am neither defending nor opposing this. It is just the way it currently is. So if no one goes and consumes food in the Dining Car, the F&B account looks the poorer for it and the train appears to be more profitable in the transportation account. OTOH if everyone goes and eats the most expensive items then the F&B account looks fatter and the transport account looks marginally thinner.
My overall position is that it is crazy to treat F&B as a separate P&L center. It should be accounted for as part of the cost and revenue of running the train, irrespective of whatever mechanism is used to entice people into partaking of the service more. That is the reason I consider discussion of how to optimize the current crazy scheme to be an utter waste of at least my time. The goal needs to be to revert back to per train P&L (if that, perhaps it should be per train set as part of an overall route structure - but that is a separate discussion), away from separate F&B P&L, and discussing how to tweak the current scheme is just feeding the Mica troll. This is the reason I ignore the discussion that you seem to reeeally want to have, and will continue to do so.
