I think it looks bad if drivers in colors are talking on cells where the public can see it, even if it's something like telling your little girl to go to bed and quit giving Mommy fits. It just leaves doubts in the bettors minds. But if you're in the paddock and realize that you forgot a piece of your horse's equip back at the barn, you can call back to the barn and have someone run it up to you. Many times I've had the race office call me in the paddock on my cell to ask me about an entry, or ask if they can use one of my horses to fill a race.
