Looking for an early retirement?

My cohort Pat witnessed a "How Not To Keep Your Job" moment today...
Pat was behind on his delivery schedule today, so he called the boss, "Bobby," to ask him to call a couple of stores, notifying them Pat was running late and needed an extension on the receiving time. That task completed, Pat reluctantly headed to a particular area grocery store. I say reluctantly, because the store's receiver, Carmen, (I'm using his real name, since he is such a class-- minus "cl"-- act. Nobody likes Carmen, because he always does anything possible to make things extremely difficult for anyone who enters his domain.)
Now, normally, receiving hours end at 1:00, but since a time extension had been approved, Pat pulled in at 1:30, knowing his delivery would be received. So did the bread vendor. Carmen staggered out onto the dock, and started yelling incoherently. "Blah-bluh-di-ahm-blurm-argh-fmph 1:30!!!!"
The bread guy coolly replied, "I called and got permission to arrive late."
Pat concurred, "So did I!"
Carmen then started ripping Pat and Bread up one side and down the other, as if they had committed a great crime against society. Bread did not have a thick skin, and was mortified at how he was being treated, so he said, "That's it. I'm getting the manager."
Moments later, the leader and vendor returned. This time, Carmen aimed his venom at his superior, leaning into a tirade of obscenities. When the manager steadfastly held his ground that he had approved these late deliveries, Carmen pushed Pat into the receiving desk, grabbed his coat, and left. CLASSIC!

Now, I'm no genius, but somehow, I don't think being so unprofessional to vendors, cussing out your boss in public and leaving without notice is the best way to keep your job!
