What do you think of a judge who admits after show they made a mistake?

If a judge is approached at the end of the show for a discussion( very civil one) and they admit to making a mistake with not only 1 class but the overall decision, does that make them more respected or less respected?  Should they stand by their decision and just say it was thier opinion for the day?  Curious to see what you all think.

Nothing is more frustrating than (sports related) an ump or ref that will make a call and then backtrack and try to change it with another blown call.  That being said, I have had this happen and it cost me a good amt of money in our premium sale.  Se told me that she would make it right, find a buyer for my calf that would continue to show him.... Etc, etc.  Lots of open ended promises that amounted to no more than me calling her asking her about it.  Basically, a huge waste of brain power.  I lost a ton of respect for her that I would not have if she would have just said, "I can see your point.  Today I liked this calf, or this group of calves and I wish you all the luck in the future." Honesty goes a log way, but false promises.....  Go nowhere! 

many of the shows I've done-- looking back I wish I would have done a few things a little differently.  During that day, I have been confident of being right-- but months later looking back and remembering-- I wish I would have done that one thing different...

All in shows with people I knew nothing about- before, during, or after.
