More Food on the Subway

Continuing yesterday's topic, if a food ban is impossible to pass and enforce on the NYC subway, are we to just let everyone eat whatever they want while underground?

While there's no stopping someone from eating, say Pad Thai while on the A train, we could maybe ask straphangers to refrain from eating something that emits an odor that would make other straphangers nearby uncomfortable.  As for consuming non-smell-irritating foods, keep it to a minimum and always remember to pick up after yourself (this applies to everything, not just food).  This is sort of like a kind reminder of one's manners, for the sake of other passengers.  This is not going to be easy, but maybe enough (and frequent) awareness campaigns can be effective.

An alternative idea is to have a designated food car and only in that area people can eat more freely.  In the place of some seats, that car can be equipped with some standing tables and trash cans.  Of course that car would have to be monitored and cleaned frequently, so that's a problem.  Maybe a small snack kiosk can be built inside that car and in exchange for allowing to sell snacks on the train they have maintain the cleanliness of that car as best as they can.
