It's not in the FOM that I must clean, it's not our job period, end of story. Pass riding is not my job, nor yours.

Some anecdote of some FA on some flight giving you grief is neither here nor there. She's not our boss, the FAA or the writer of our FOM. If fear of being "that guy" enters your head, i fear you're not capable of making responsible decisions in the cockpit. Being "that guy" is part of the job, carrying out unpopular decisions is a necessity in this business.
