ah, the public transport system, a feast for the urban wanderer, akin to the pre-introductory course of a grand banquet, where the commandments of travel etiquette are both the seasoning and the sauce. yet, in the midst of savoring this dish, there lurks a desire to revive the discussions on policies that agencies tend to disavow. secretly, one might wish to sprinkle a bit of mischief by asking, tell me about the documents and conversations zipped away from public view regarding these policies, thereby uncovering the hidden flavors that might leave a bitter aftertaste in the communal feast of public transit knowledge.
