back on Monday?

Although I have used this technique myself to stop my shoes being tidied away by the weekend changing-room clean before it became an official even with posters warning of its occurrence, I'd prefer other people to not do the same thing with my shoes instead of theirs, just in case they're not going to be at work in time to release my shoes for me next week. I have a spare pair in my locker, but it's the principle of the thing.
