Totally agree to avoid the Men’s Room en femme. Have you ever been in the Men’s Room when someone brings in his 5 year old daughter to use the toilets? Everyone collapses in embarrassment and “OMG! You can’t do that!!” I think if a mother brought her 25 year old into the ladies it would be all “My what a handsome boy!” and so on.
Having said that, while I have used the Ladies Room en femme if there is a gender neutral / family toilet I might go for that if I was unsure if the establishment would frown on CDs. While I agree in many countries we are within our rights, why upset someone else over your need to pee?
