God bless her, she handled it well. My worst mistake on TV was racking the balls for 9-Ball with the nine in the back. Lucky for me, the player who was breaking pointed out my error. How I did that I don't know to this day.
I did fall asleep on my feet over 30 years ago at the big tourney in Bend, Oregon. I had been ref'ing all day, and on my feet the whole time. Jim Rempe kicked at a ball and I have no idea if he made a good hit or not. I was dozing off. Fortunately, several people in the crowd nearby came to my rescue. After that I never stood on my feet more than a couple of hours without sitting down. I never knew you could fall asleep standing up, but you can.
