Interest on checking account.
About nothing? I put my part time job check in a small account to pay most of my bills. Keep less than a grand or two in it and get about 3 cents a month interest on it.
So, now I go inside to make the deposit and grab a couple of their free ink pens every time. I have a friend with a business that hands out the same pens. Cost him 40 cents each. I'm getting about 3 bucks a month in pens. Never buy any and pass some out to friends.
I'm on a fat free, sugar free diet. So, I can also grab a free sucker, because it's free.

grab everything you can, I do some similar things, just for the principle if nothing else. Use their restroom before you leave if you need might save you a bit of water at home. At work charge your cell phone on their electric, fill a cup with water for the drive home, even if you don't drink it all there is a plant or the grass that can use the rest. Don't forget to return those bank credit card offer postage paid envelopes (empty of course, oops forgot to include the form 
) to help the USPS & to let them have their trash back.
