I chased the last guy. Threw him into a wall. The wall won. Told him I don't want the likes of him to come around again.
He came around the following week. He's actually a nice guy. Did a deal for all channels for around $300, that included all sports. That was a year ago. He comes around for a beer now and again. Keeps showing the scars from that night with his toothless grin for his missing molar.
I guess your "deterrence" did'nt work then if he came around again the following week, but this time to your benefit by getting you a decent package, hehehe.
