I am with you, they used to walk all over me back in the days when I even thought about being nice, but what you do with the shovel that scares me because it is criminal ... Not to say I've never done something criminal, for me nothing worked quite like grabbing someone by the throat to get the message across. Still, it's criminal and I don't like being scared (the mere possibility of going to jail scares me really bad). So I stopped using those tacticts. Now I use psychological warfare myself, the bit with the supermarket is new to me but I like that one a LOT (nothing criminal about it, for one). I also like driving past their house FREQUENTLY and SLOWLY, thou that one is 50-50, only works sometimes. The newest one I found that works real good is showing up and taking pictures with a digital camera ad nauseaum. You could use a regular camera without film as well, the point here isn't the pictures, but you're hoping someone sees you doing it without you being obvious about it. NEVER, EVER start an argument unless you're ready and willing to have the last word by ending it QUICK either physically or with the threat of it, if need be. Shouting matches suck and never end and you don't get paid unless you somehow shut them up (and unfortunately, shutting them up usually involves either a fight, a punch, or the threat of it - ah yes, there goes that criminal aspect again). The argument scenario is one reason I don't like talking to ppls who owe me money, I don't even answer the phone when they call because all I want is my check, and not some never-ending blablabla. But the supermarket bit, that one is a nice exception until you run into one that don't mind showing their own arse a bit... Unlikely, thou.
