Whether in your local restaurant or in an international airport, there are some essential restroom rules that every man should follow. Remember these, and maybe you'll make the experience easier:
Respect the Urinal Gap
Unless you want to be weird, try to keep at least one urinal between you and the next user. Personal space is real, especially in America. This understood boundary prevents accidental splashes and maximizes comfort for everyone in the restroom.
Washing Your Hands is Mandatory
Somewhere along the way, someone decided that washing your hands in public places wasn't necessary, and wiping them on your pants is fine. It's incredible that I have to say this, but people see you. I always remember those who didn't wash their hands when we were in the bathroom for future reference. I don't trust them in any area of hygiene or personal cleanliness, and often times it's an indicator of poor social skills.
Three Shakes and You're Out
If you're using the urinal, the rule is that you get three shakes of the "hand," and then after that, you're playing with yourself, plain and simple. Don't take forever to shake the snake, it isn't necessary, and people hate seeing that experience from afar while anxiously waiting to utilize the facilities.
Never Touch Another
You see this in comedy movies and think its funny, but don't ever actually do this. Never touch another man while he's using the bathroom. This is the ultimate violation of personal space. In fact, try to give a 2 to 3 ft space when speaking to another man in the restroom.
Flush It
I know that you never want to touch the public restroom amenities but don't be afraid to use your shoe. Just don't leave logs at the cabin.
For men, oftentimes, the standards for cleanliness are pretty low, but with that being said, some basics need to be adhered to. In some cases, violations of these simple rules can result in a physical fight or even a loss of a job. Do yourself and us a favor, stick to the public bathroom basics.
