Everybody upstairs, don't get me wrong. . . I've had the same experience. I paid the money and bought something. The clerk packed the bag and opened the receipt.

That thing seems to fall off. If it is strong, it can be torn off. But in general, you should need professional equipment to open it. This kind of thing is fixed by magnetism.
