Subject: Re: Favorite Charley Quotes
“Any time you go to a football game or a function there’s a huge line outside the women’s bathroom. Who doesn’t know that they pee in a different way than the men?” Munger told The Wall Street Journal in 2019. “What kind of idiot would make the men’s bathroom and the women’s bathroom the same size? The answer is, a normal architect!”

Long ago I was studying to become an architect. This subject was covered.
Some folks did a big analysis on this specific effect. The big factor not mentioned by Charlie is perhaps a bit of a generalization, but in this case an inevitable one: sometimes ladies at sporting events get bored more, too, and are more likely to use the facilities during any average event.
Consequently the recommended rule was to allocate three times the space to the ladies' washrooms as to the men's.
