A sure sign

Have we humans got to the point where we have so little sense that we need to be constantly reminded of the most basic things?
Basically, I'm asking because of the sign onslaught in the bathrooms at work.  It struck me the other day that there's almost nowhere that I can look to avoid being reminded to behave in some way that should be automatic.

Inside the cubicle, two different stickers instruct me on what can go in the sanitary bin and what cannot.
I get out, and am reminded not to flush paper hand towels down the loo, as it causes blockages.  I'm not surprised, because even toilet paper seems to do that in this special ablutions block.
When I do put hand towels in the bin, there's a sign to remind me to compress them to save space.

The far wall reminds me to keep things tidy and be considerate, because this is a space shared with others (though hopefully not the same cubicle at the same time).  Given that women have a reputation for being the tidier sex, it makes me wonder how many signs there are in the men's bathrooms - not enough to find out for myself, though.

I head back to work, but not without a last insulting sign.  This one has the audacity to call my hands a  "germ farm."
I think I'll go back to my desk for some peace.
