1. Allow Personal Space
When you go into a restroom, don't crowd other people. Be respectful of the personal space of others. Men, unless the restroom is crowded, skip a urinal to prevent someone else from being uncomfortable. And never look at another man as he does his business.
2. Ignore Your Cell Phone
Don't chat on your cell phone while using the restroom. The person in the next stall over doesn't need to know the details of your personal life. And you certainly don't want the person on the other end of the line to have to listen to the loud flush. That's just rude.
3. Flush the Toilet and Cover the Evidence
Before you leave the restroom, make sure you flush the toilet. Stick around and check to see if everything has been whisked away. You don't need to leave something behind for the next person to deal with.
If you are in someone's home, you may need to flush more than once to reduce sounds or lingering smells. Use an overhead fan if one is available. Some people carry small containers of air freshener for this purpose but remember that your host or other guests may have allergies.
4. Dispose of Personal Hygiene Products
Anything you use for personal hygiene needs to be wrapped and disposed of in a trash receptacle. Avoid flushing anything but toilet paper because it might clog the system.
5. Replace Supplies
If you use the last of the toilet paper, soap, or paper towels, show respect for the next person and replace it. However, if you don't see spare ones lying around, inform someone that this needs to be taken care of.
