Locker room at my gym has five shower stalls, each one three walls and an opaque curtain. Four of them are 24" (?) square; the fifth is perhaps 24" x 36" and includes a bench seat for handicapped persons.
Many, many times I have seen someone who gets in the shower fully clothed, then tosses his used clothing out from behind the closed curtain. After showering, they then somehow manage to dress within that confined 24" space.
I honestly can't figure out how they do it. At the very least, they must use their towel to dry off the walls - how else could you dress in such a confined space without getting everything wet?
