Used to do odd jobs at a stable when I was boarding my horse, earning money to help cover the board and lessons.
The owners had about a hundred boards, plus a string of around 20 rental horses and "project horses" being trained for resale. One time, they rented a couple of horses and an arena to somebody shooting a "horse safety" movie.
*I* was handed the lead rope of one of the ugliest horses I've ever seen by the wife of the husband and wife team who owned the place. She to make him pretty for the movie crews. This horse was covered in scars and just UGLY. No mane or tail, either -- his tail had been docked. Plus, covered in manure. Anyway, I did my best, including clipping the little turd per her directions. (Did I mention he had a bad disposition and clipping him took some doing and assistance from a couple of the resident cowboys?)
Two hours later, the husband walks by and throws a fit that I'm grooming the horse. He takes the horse away (not entirely clipped) and comes back with a very pretty nut case who was, uh, not suitable for a video on horse safety, unless they wanted to demonstrate how to get hurt. At least he had better ground manners ... so I get THAT one cleaned up.
Along comes the producer, who throws a fit that the horse is the wrong color. He wanted a grey with a long mane and tail -- something the stable didn't own. He marches off, gets the wife, who goes, "Well, you own a grey, don't you?"
Just so happened I did. So I get my OWN horse -- who was actually fairly suitable for the job. Get her cleaned up. The producer's thrilled (my horse was the right kind of photogenic for the job, and the right color to film well) the wife shrugs and is happy. Everybody's happy.
Along comes the husband, who throws a fit that I've substituted my own horse at me, then at the producer and his wife. He apparently wanted his own pretty horse in the movie, ego thing.
They never did get the commercial shot ... I think the producer took his business elsewhere. LOL!
