Well at least parents will know where to go to find menstrual products when their daughter needs one when out in public. I suspect the women’s bathroom facilities will be empty of any, but they can always wait until the men’s room is clear and dash in to grab what they need.
People will be stocking up at the restrooms. And then there won’t be any sanitary supplies in the restrooms.
At least, now you can ask your husband to get you one.
