Well with four urinals, the decisions start to really pile up. Even if
all four urinals are empty upon your arrival, there is still a lot of
thinking to do. Ideally, you should still choose a nice, clean smelling
urinal at either one of the ends. However, certain extenuating
circumstances have set precedence for the selection of one of the two
inner urinals. The reason that this is acceptable is that the selection of
an inner urinal does not decrease the potential M.P.P.N.B.A. (Maximum
People Peeing Not Beside Anyone). Therefore, if, say, a large deposit of
nuclear waste has located itself in BOTH of the end urinals, an inner
urinal may be employed, preferably the one farthest away from the largest
nuclear waste deposit.
What about if someone is already there? Well, much like the other
situations, pee if you can without peeing beside anyone,
and otherwise lapse into delay tactics or stall deceit strategy. In fact,
because the MPPNBA's are identical for three and four urinals, etiquette
is greatly preserved across the platforms.
