The wardrobe lock needs a 1 EUR or 2 EUR pledge. Staff members warned me, that putting a 1 EUR coin into the 2 EUR slot would make the lock unusuable, i.e. the “wrong” coin does not fall down to the output tray. The lock must be screwed off the wardrobe for opening and removing the wrong coin

. Staff members told me, that once, when opening the lock, the staff found 4 wrong 1 EUR coins.
