Letter

The other day my utility company mailed me an informational type letter and did not put a stamp on it.  To my surprise the letter was still delivered but Canada Post had attached a "$1.04 Postage Due" card.

"With this card you received mail that was sent without enough postage.  To avoid delay and inconvenience, the amount due was not collected at the time of delivery.  Please affix the postage on the other side of this card to cover the amount due, and mail the card.  Your postmaster".
