Why do architects give more restroom toilets/urinals to men, when it takes women longer to go?

I’m constantly ranting to my husband at public places that there’s a huge line for the women’s restroom while men walk in and walk out, then stand there for 15 minutes waiting for their girlfriend/wife/sister/friend etc.

I’m at an airport and both the men’s and women’s entrance doors were propped open. The men had 4 toilet stalls and 3 urinals while the women only had 2 stalls. WHY?!?!
