What do tour groups usually post for tourists to use or eat?

Recently, many tour groups send things, such as chickens, ducks and geese. If you meet these tour groups after signing up, they will definitely take you to spend money, almost all of them are shopping spots. What's even more ridiculous is that if the group doesn't buy much after arrival, when all the tourists get on the bus and are ready to leave, the sales staff in the shopping area will follow them and continue to sell them in the car and ask you to buy them. Don't buy it, don't let it go. Super scary.
