About 10 years ago a former coworker sent out some sub par workmanship to a customer. He happened to be out sick the day the customer came calling to "discuss" the quality of the work. I got a dressing down the likes of which I hadn't been on the receiving end of since my days in the Marines. I sat there and took it even though I wasn't responsible because the customer was correct, the workmanship was abysmal. This letter brought a smile to my face.
