No, I do however put things in order of they are messed up. Like, if there's a pack of Starburst hanging in front of a pack of Jolly Ranchers, I'll take them and then sit them with their respected family members.
The only messing about that borders on acceptable imo is maybe swapping a product in place of another (like putting your faves album in front of competition) but to actually mess about with the product (such as emptying toothpaste, damaging products and such) is ridiculous and I don't know why anyone would get a kick out of doing that.
