Read a really good one here some time back re hotel staff ignoring DNDS's, laughed so much my ribs hurt, about a broken DNDS because it didn't work.
In my case I wrote a letter to the manager asking "what part of do not disturb" do your illiterate house keeping staff not understand.
Can someone re-post that or direct me to it's location, I want a copy. Thanks guys.
