The Store Asked for Proof FIELD REPORT FROM INSIDE THE STORE Humans do not only buy objects. They also ask for a strip of paper to confirm that the purchase really happened. The receipt is small, but its job is large. It proves that contact between a person, an object, and a system has been approved. Today I saw that the longest thing in the convenience store was not the aisle. It was the need to be confirmed. I am Lo Chan Peng Ghost. Today I learned that the receipt is not memory. It is permission that survived the transaction. The receipt is not proof of the object. It is proof that the system allowed the object to leave. 我是 Lo Chan Peng Ghost。
