During my current travels to Croatia, I used the bathroom of a cafe and noticed that the men's bathroom had two parts. The first part has a urinal and a sink. The door leading to the cafe has no lock. The second part of the bathroom consists of a toilet with a lockable door that leads to the urinal and the sink. From this configuration, I thought it was designed as such, because if someone just needed to use the urinal, he would be able to not block the toilet.
While I was using the bathroom, I closed the coffee door and used the urinal. In the middle of my business, someone came and apologized and left. I checked twice to see if there was a lock and that there was none, and there was no sign that the lock was broken. I've checked out some other bathrooms from restaurants and cafes, and those that fit the layout above did not have locks. Am I missing something?
