This happened to me many years ago. I was a DC 9 pilot. MGM to ATL. copilot came and found me and said that we would have to fly back to ATL at 10,000 feet. I asked him why. Answer was ATL was WXAF and A/C holding at all altitudes, all quadrants. I called dispatcher for more gas. Big argument insued. anyway, after a screaming argument, i got the gas. Got to ATL, went to see the chief pilot, told the entire story and asked "Was I wrong?". He answered "Yes you were...you argued when you had already won the argument". I kept that piece of info in mind for the rest of my airline career. Some good advice, I think. Also keeps the blood pressure down.
