I follow a strict set of rules in bathrooms both public and private. For example, I don't use the public urinal for short people and young boys that is set closer to the floor, because I have a moral objection to getting pee on my ankles. Similarly, I don't talk to other people while I'm using the toilet, washing my hands, or entering or exiting the bathroom because I'm attending to a biological necessity, not mingling at a social event.
I recognize that some of my ideas may seem a little extreme, but for the love of god, NO ONE should EVER bring a beverage into the bathroom. That's not just some crazy tinfoil hattery I'm spouting, but an honest-to-god safety issue. When you bring your morning coffee into the bathroom with you at work, you're inviting your coworkers to go to the bathroom in your mouth.
I'm serious. Dr. Charles Gerba studied the effects of flushing toilets and found that not only is a germ-and-virus aerosol spray ejected from the toilet every time you flush, but that water droplets from the toilet can remain suspended in the air for up to two hours after the flush. That means that your steaming cup of coffee is sitting there collecting aerosolized water droplets from the leavings of everyone who has gone through that bathroom before you. How well do you know your coworkers? Do you really want to get to know them that much more intimately?
You'd have to some kind of lunatic to drink morning coffee that you've carried into the office toilet, and yet some of my coworkers regularly carry drinks of all kinds into the bathroom with wild abandon. It just makes my skin crawl.
