SIGNS OF THE TIMES #1

I do love a good bureaucratic sign.  You know the kind that makes you feel about 3 years old.  For some reason, lots of them seem to be found in toilets and are usually the ones written in a nagging voice.  Like this for instance, found at the HQ of Job Centre + in Cambridge.

Does anyone have a sign like this in their toilet at home?  No?  Why not?  Is it because we're not fucking stupid?  Things like this really wind me up.  I hate being lectured by an anonymous voice hiding behind a bold font and/or underlining.  It's time to name, shame and stop the madness.  

Post your examples.... let's have a competition!
