I get it.
I get why, on occasion, you'll run into a bathroom with no little privacy wall to shade your junk from the unsuspecting eyes of every bar patron unfortunate enough to wander in while you've got your dick on full display.
It's because of vandalism: Drunken assholes and teenagers will take the existence of an unadorned dong-blocker as a challenge, and will invariably write some homophobic, sexist, or racist slur on it. This is because the only way they know how to make their mark on the world is to leave it a slightly worse place. Pity them, for their plight is tragic.
But that explains why the urinal wall was removed -- not why it was never there in the first place. A removed urinal wall is society's time-out corner: We proved we could not be trusted with such a sacred responsibility, and our punishment is to flash our junk to a bunch of drunken rednecks every time we burn through a whiskey sour, or else stand way too close to a bowl full of strangers' pee and risk splash-back. But there is no rational explanation for a public bathroom intentionally built without any urinal walls in the first place.
For example: In my town, the bathroom of every single Regal Cinemas features a wall of 20 urinals, always positioned directly parallel to the entry door. If you're looking even slightly downward when you enter -- say, at a cellphone -- you are guaranteed to see another man's penis. If you were the unlucky pisser, that's a mandatory minor sex crime every time you use the facilities.
What are the possible explanations for this? Are the designers of bathrooms so far removed from society that they don't consider genital privacy in their layout? Are the owners of Regal Cinemas prior sex offenders who just want to show the other side how it feels? Almost certainly.
But that's irrelevant: I posit that this can only be the work of a cold and unfeeling conspiracy designed to either irreparably damage our bladders or permanently lower our morale after the post-Shrek crowd wanders into the toilet to hastily evaluate our wangs and finds them wanting.
