I had one that swore to the homeowner that it wasn't possible that we were going to send 4 cable boxes to 11 TV's...had no idea how an HDMI matrix worked, and couldn't wrap his head around it when I tried explaining it to him. Kept telling the homeowner that it wasn't possible and the cable boxes copy protection would block it from happening. He literally hung out at the house the whole day, then once he saw it working he called his supervisor to tell them that we were "hooking up some gadgets to steal cable"- when the homeowner overheard that call, he kicked the guy off the property.

Thank god for CXI.
