No.
Actually, I may see more signs of stress when the attendants are trying to put horses in the stalls. Horses are claustrophobic by nature. They don't like to go into small, enclosed places, so when you put them in the crates with friends, they actually load quite quickly.
I have the video, and I am happy to show you the video I have taken right there when the horses are loaded in the crates, and how they're loaded. Yes, that's our average time to load.
