What little thing do you do to make the world a better place? I'll start: I try to forcefully pee away the poop stains in the bowls of public toilets.

I go to extreme lengths to return lost cell phones, purses, and wallets to their owners. I go though address books and text messages, to find phone numbers for 'Home', 'Dad', 'Mom', 'Work' or some other number that I can call to pass on a message to the owner. If it's locked I keep it charged and on me until someone calls, then I tell them that it's lost and the owner needs to call it so we can arrange for them to come get it. For the wallets I look at business cards and IDs and do a reverse directory lookup for a phone number but if their number is not listed (as with most cell phones) I try and find a Facebook or email account and send them a message. I clean three bars daily, so I've probably done this for at least a phone and/or a wallet/purse a week for the past two years, usually more.
