You are right. I've never been an installer. But I do have a job. When I am told to do something for work by the firm's operating manager for my section, and to have it done by a certain time, I do. There is no excuse. When I say I will do something for a client at a certain time, I do it. There is no excuse. I don't see what is so complicated about that. Again, I don't care why they were late or did a bad job. I only care that a bad job was done.
