Most bathrooms feature urinals arranged in a single row. It may be 1, 3 or 12 urinals, but most often they are just one beside another along a single wall. Sometimes, urinals occupy opposite sides of the room. And sometimes, you get the dreaded corner urinal.
My advice is to avoid these at all costs. In theory, you could treat the entire set of urinals as if they were on a single wall, and just follow the “don’t pee beside anybody” rule. In practice though, if you choose one of the urinals in a corner, and somebody else comes and occupies the other one, all hell is going to break loose.
