The thing about reptile shows.....
temperments of any cold blooded animal is hard to judge. The animals are not heated on those tables, most of the time. So, they cool down and become less fidgetty, more calm. I got a tegu and a savanna monitor at a show. Very well behaved, let me hold them, whatever. Get them home and warm them up, turned into evil little hissing, biting, tail lashing monsters. LOL.
If it is a baby, tail rattling is normal. Handle it and it will get used to be touched, picked up. If it is an adult, or sub adult, it might just need to get used to you or that might be the snake's temperment.
Good luck
