Hmm, in the "good old days", people didn't seem to have a problem deciding on which bathroom to use.
Mr. (oops) Mrs. Kohler doesn't care.
My brother-in-law built a $900k house and put in a urinal so he wouldn't have to have a conversation with my dopey sister. BTW, non of us piss on the floor. Further, we put the TOP down on the John. (I hate to see an open toil-lette).
