I have a theory that there's a room full of people sitting at typewriters somewhere in Winnipeg creating these receipts and manually feeding them into fax machines. Naturally, they occasionally make mistakes. This would also explain why it takes so long for AC to get them to us.
That's a good one.. haha.. Maybe they put a rush on mine when I call them earlier to request mine to be faxed to me right away and I got it within 3 mins!
