“You never know when you’ll have to change out of costume in a public bathroom with a coin deposit slot.” By the way, America doesn’t really have these–public restrooms are free. The upside is that in the direst of emergencies you never have to worry, but it doesn’t do wonders for their cleanliness.
Ah.
In Norway, most public restrooms are free, but this does happen sometimes. More commonly, though, you may have to ask for a key or for the restroom to be unlocked by staff where you are, but even that’s not something you see all that many places. At least not up here in the north.
