The law requires that public places have toilets and urinals. So government offices, civic offices, colleges, hospitals and such have these things. The conventional design is shown as A. There is the ceramic bowl fitted in the wall. A guy has to stand in front of it and do his thing. The output is carried to a drainage channel near the floor through a pipe fitted at the bottom of the bowl. This pipe has a crucial role, which one can understand only when it is missing. About 30 to 70% of the urinals have these pipes missing. This percentage can be used as an index of the level of maintenance of these public places. If one uses such a urinal, the output falls to the floor under gravity, and its drops bounce back to spray one's trousers. The resultant embarrassment during the remaining part of the day is self evident. I caution people visiting the places mentioned above. If the pipe is missing, try another urinal, no matter how urgent the business might be, unless you plan to go home for a change of clothes.
