not to the extreme of this but on a regular (2-3 times a month) I will have time warner monkeys unplug one of my hdmi's or electrical plugs to install their equipment. So then you're left with the great scenario of charging the client and make them go to TW for reimbursement all over the installers stupidity.
One thing I have learned in this industry. It is easier to pull a wire than it is to push one.
