I tend to harbour plans for guerilla office maintenance. For example, the bathrooms at my current place of work feature too few paper towels for a typical day and one bin that is too small for the towels that are used. I figure I could buy a large-ish plastic bin and just leave it there myself, fixing the problem and creating a better work atmosphere for myself and others. I also note that there is far too little cutlery to go around at lunchtime, and I wonder how to get around that problem, too - probably by buying forks and teaspoons in bulk.
To date, I have not enacted any of my plans in any workplace. It's not the money. It's more the expectation that I'll get a "concerned" email saying "Some time last week, a mysterious extra bin appeared in the men's bathrooms on level 8. Security were called, the building evacuated and the plastic bin destroyed with extreme prejudice. It turned out to be just a bin, but this incident illustrates the need for vigilant employee security blah blah blah". Basically, I don't trust that upper management encourages this kind of pseudo-nesting behaviour.

PS - I just see a problem with an easy solution and I want to help.
PPS - The best I've done is carry in extra paper towels from the kitchen.
