Parasites in Express Delivery Stations

I opened an express delivery station in the community. Unexpectedly, he was targeted by the elders and aunts in the community. They "check in" at my express delivery station on time every day and stand at the door picking up cardboard boxes. If you can't pick it up, take it. If you can't pick it up, grab it. If you can't grab it, steal it. He said with a good name: "These express packages will be opened in the end anyway, and the cartons will be thrown away by you people. Why should I open them first?"
