<human>: Could you distill the essence of the text into 1-3 sentences?

The last few times I've been to a club I usually get a few coins back in change from the bar. These coins I throw in the urinals, one in each. I check back in about one hour, just to see how many coins are gone. 
I have been doin this for a while, and at first I started out with 1kr coins (ca: 15 cents). Usually no coins have dissapeared. The next time  i threw a 5kr coin in each (ca:80c), and this is when things starts to get a bit interesting. maybe a coin or two have dissapeared. 
Then, tonight, I threw one 10kr coin on each of the six urinals. After about half an hour all the coins are gone. These coins would at least buy you a beer. 
The point? I want to know how far some people would go in order for a few bucks. Me personally would never pick up anything of such a small value that at least 50 strangers have pissed on. 
so, how far would you (drunkenly) go in order go earn a few bucks? Have you done any small social experience such as this yourself?
