I just came back from Amsterdam and Brujes, Belgium where you pay to use almost all of the public
bathrooms. I took a half of an Immodium every other day when i was there and that semed to keep things in check, but wondered what I would have done if I was having problems. Some of the places have a person that can dispense change, but most of the facilities require you to insert coins into a slot to admit you to the bathroom.
