Its probably the jet lag but this has made me laugh all day every time I went to the elevator in our US office.
On the opposite wall is a big white cabinet with 'First Aid' in bold letters on it. Understandably obvious.
If one were to put a small box on top of the first aid cabinet it could be viewed as being of even more importance, worthy of displaying it outside the first aid cabinet itself.
On top of our first aid cabinet is a box with big bold red writing on it stating it is a 'bodily fluid disposal kit'...................I don't think I want to know why that would be of such great importance
