Psychic Powers

We recently received a wad of cash in the mail.
There was no accompanying citation.
There was no return address.
There was no information whatsoever.
We could not process the payment.
Do you expect us to be psychic?
Do you expect us to close our eyes, touch an envelope, and claim your personal details?
The wad of cash sits in the office safe, untouched. It has been a month, and no one has claimed it.
