Indicators of toilet occupation.

111: Imho is excessive. You ate there...why? It is enough to check the hole at the top of the door so that the burning light can see what is occupied.

222: only do not forget to close the hole with a glass, or will pull out of the sort through the hole, if few people have failed to have breakfast.

333: Just so I see a laurel laying a glass. Scotch and all the affairs :))) The door is a bar. In the army sort, even without light, you can see where it is occupied.
