I think the only fuckup of urinal use is to walk up and not be able to piss desperately when you pull your dick out. Any pause means that pee shy has made an appearance and only gets worse as the clock ticks. Or it means you came for some action. One can be mistaken for the other, but either way, you failed the 'real man' test.
At my office, there are two urinals, with sufficient partition so that you would have to tilt your head in an obvious way to check-out the other guy's stuff. Even so, just the pee-shy factor (the sound) makes it so none of us can pee next to a co-worker. We've written an unspoken rule that the second guy has to use the stall.
I feel like this is a newer concept, and that society is getting more uptight. Of course the Indian coworker is exempt from all this (different cultural rules), and so is anyone from another office.
