I tipped my cable installer. When he was leaving, I asked him how much it would be for an extra digital box. He said, "well, it's 6 bucks a month, but you can have this extra one in my truck." So now I have an extra cable box for my welf friend who doesnt have a cable ready TV and I get to charge him the extra money for the cable bill when he decides to be an a$$hole about stuff.
Tip well. It pays.
