I've had airport agents who know me particularly well either ask me privately (after a they encounter something new) or introduce a other customer to me with some of the "finer details".... The truth is I/we love in the system traveling from one cog and gear to the next; they're simply a gear (or perhaps even just a few teeth on a gear) in a giant machine... They know what they're required to know really well but all of the other little details, particularly those that don't pop up every day like YBM, may not be quickly at hand
