We have something in common regardless of age, income or marital status –– everyone uses the bathroom. (I’m sure we have more in common than that, but we’re focusing on bathroom habits today.)
There are some universal etiquette behaviors that you assume everyone is aware of, but I’ve used enough public bathrooms to know this is not the case.
It’s important to wash your hands, change the toilet paper roll if you can, and to leave the bathroom as clean as you’ve found it. If there’s a line, don’t be a jerk and waste time in there.
Always lock the door to protect yourself and any innocent bystanders who may walk in.
For men using urinals, it’s important to never make eye contact and leave as much space as possible. (I’ve never dealt with this, but my husband tells me it’s very awkward when someone ignores these unspoken rules.)
Also, stand close to the toilet while you’re using it. Women, this is not the time to hover a mile away! Once you’re done, don’t forget to flush. It really doesn’t have to be hard, folks.
While we’re on the topic, you have to take a look at our post on the bowel habits of the average American.
