There is always a small shop deep in the alley. During the day, there is always a piece of paper on the door of the shop saying "The shop is closed and does not recycle." The neighbors do not know what the specific recycling of this shop is. They only know that this shop keeps changing owners. And in the evening, the shop put up a "free recycling" sign and recycle everything.
Oh, by the way, do you have anything to recycle?
