Though it is talk, it is good to inform those in the area that might have the misfortune to deal with these ****heads. If they tried that **** in my here, more than a few people would take care of them. (That's being nice).
Another reason never to pay with cash. I've had some problems with customer service and products bought over the years. As soon as they give you a hard time, just call your credit card company and file a complaint. They'll do a charge back and credit your account as long as you tried to fix the problem in good faith.
