I thought that it was designed as so because if someone just needed to use the urinal they would be able to and not block the toilet.
...
I checked a few other bathrooms from restaurants and cafes, and the ones that matched layout above didn't have a lock. Am I missing something?
Yes. If the outer room with sink and urinal were intended to be a place of total privacy, there would be no need to separate it from the inner room with the toilet. In other words, if the outer door had a lock, someone using the urinal would be blocking access to the toilet whether or not there was an inner door separating the toilet from the urinal and sink.
How to use a 2 part bathroom where the urinal and toilet are separate?
In the normal way! If you are uncomfortable with someone walking in from the cafe (or from the toilet for that matter) while you are peeing, you can wait for the toilet and pee in there with the door locked.

Urinoirs usually don't have any locks - if you just need to do № 1 use the urinal if you are comfortable with that.
If you need to do № 2, or if you are uncomfortable with urinals, use the real toilet.
№ 1: "Do the part of your business you can do standing up"
№ 2: "Do the part for which you should be sitting down"
