of all the gin joints

When there are six cubicles in a public latrine, five of which are vacant, why on earth would ANYONE choose to take the cubicle that IS directly beside the occupied cubicle. WHY?

 Who are these needy people?! Why have they no sense of proivacy, prickliness or prudishness?! Granted there is NO NEED to ask who the uptight person/people is/are (oh the conjugational bliss of such an inclusive exclamation)! I just cannot understand  or abide it. This was too long for twitter.
