I can provide some general advice on restroom etiquette.
In most cultures, there is an unwritten rule of giving others personal space in public restrooms whenever possible. If there are multiple urinals available, it's generally recommended to leave at least one urinal's space between you and any other person using a urinal. This practice helps maintain privacy and avoids discomfort for both individuals.
If someone enters the restroom and stands at the urinal next to you when there are other urinals available, it might be a good idea to use an available urinal that provides more distance between you and the other person. Doing so can help respect each other's personal space and make the experience more comfortable for both parties.
However, every situation is different, and individual preferences may vary. Some people may not mind using urinals next to each other, while others might prefer more privacy. It's essential to be aware of your surroundings and respect the personal space of others in public facilities.
