Just a few quick suggestions...

When you're returning something at Home Cheapo, don't give the person at the return desk a  mangled box that is held together with masking tape and looks like it fell of the back of a truck going 80 MPH and then be surprised if that person needs to ask the returns department manager what to do with it. Also, when they ask you if you have your sales receipt, have it.

If you're out for a walk with your children and you're pushing a baby in a carriage, if there is a sidewalk available to walk on, use it, as opposed to walking in the middle of the street. I know, it might sound a little crazy, but give it a try...

I hope you find these suggestions helpful!
