An ordinary trip to the bathroom not only offers relief, but also provides a moment of respite from the storm of conference calls or oversharing roommates that may be waiting outside. So maybe it shouldn't be surprising to enter a communal water closet and find a fella hunched over a urinal, resting his head against his forearm as it's propped against the wall and dangling a half-eaten corned beef sandwich in his hand. Or to hear a woman munching an apple in the next stall. But that doesn't make it any less unsanitary (and just gross) to dine on the can. If not for your own personal hygiene, refrain from noshing for the benefit of others. Who wants to smell corned beef or hear that apple while trying to take care of "business"?
