How's this one? Working for Dish, you get a W/O for a receiver exchange with a 500 Dish upgrade. The customer has a 300 Dish and a 3200 receiver to be swapped out for a 501. You get there and tear off the 300 dish and plant the 5oo dish, que it in on the roof, hook up the coax and go in the house to find out the receiver is bad and has to be RA'd. Now you didn't finish the job so you can't close it out. No pay ID. And no assurance your sorry butt is going back to drop the new 501 in so you can close the job and get paid. Some other tech or some other company even, may get the new work order and thank the first tech for doing 7/8's of the job.
