Some women’s bathrooms have machines from which you can buy a tampon or menstrual pad for roughly 25 cents or so. In the Philadephia airport yesterday, I walked into the bathroom and there was a pile of tampons sitting on the counter (see above photo). It reminded me of my boarding school which had a bathroom in the main administration building that some of us girls learned had a free stash of tampons in the cabinets underneath the sink where the extra rolls of toilet paper were kept. Quite a few girls hoarded tampons over the years at boarding school and even had enough for breaks, or summer time, or their post-high school years in college. Why buy them if you can get them for free?
