Yeah - cause every home in America has a urinal in it. Right.
It certainly has the equivalent.
You speak as if you have never been to a public venue where the men's room is no waiting and the women are lined up at the women's room door. Recent construction probably dedicates more room for the women's room than in the past, so that might not be the problem it once was.
Because at home men tend to be more respectful of the women and girls in their lives. Not so much in public restrooms. So men need a large target — a urinal.
