It is never good to have the boss mad about anything. When I worked in my fctory job before I retired I had a boss who was always going off on someone. One day it was my turn. I was in the welding shop in he comes all red in the face. He starts in on my about something. After about 30 seconds he looks at his shoe which is smoking. He was standing on a red hot piece of metal I had just cut off. He grabs his shoe off, and starts in about his new shoe being ruined and walkes off with one shoe on, and one shoe off. Every one in the shop got a good laugh out of that. He never finished chewing me out. He was really a good boss he just had a problem of instant rage about nothing. Stan
