Maybe I've been wearing incredibly cheap plugs but I've found after a couple of hours of being plugged that *ahem* gasses that would naturally be expelled build up fiercely and cause urgent internal pressure to expel. Very hard to resist. Those gasses must go somewhere.
(btw, the ladylike way to retrieve a plug that's falling out in the street is to move quickly to the side, put your bag down and crouch behind it as if you're searching for something. Then it's a discreet move from pavement to bag. Wish I'd realised this before 'the incident' and not after.)
