To the alternative couple that decided to have "private time" alone on the 6:13 from Princeton Junction to NYP yesterday...
... Which one of you doesn't know how to flush a toilet? Please pick one way to disappoint an entire train car full of people and at least press a button so the next person doesn't have to. Don't decide to have "funsies" on the train and leave the remains of your meal for someone else to find. Try to at least pretend to have a molecule of a modicum of decency. Thank you.
