I've spent thousands at ct, don't hate
Canadian Tire has been doing business across Canada for over 50 years. Several hundred thousand people (at least) could make a similar claim. It doesn't justify petty fraud, though I suspect you know that.
Considering the number of sales CT has each week (and can vary between associate stores on a national scale), I'm surprised a receipt wasn't required. It's a well-worn scam as old as retail shopping itself.
