This will affect more than just retail clerks. As a government employee, I get a discount on Apple store products. I bought an ipad yesterday and got a whopping 9 dollar discount. I suppose I have to declare that as income?
And what of academics who get a discount at their bookstore or at the Microsoft/Apple store? Or how about those of us who use coupons? Should that be taxed as well? This government/CRA has gone crazy. These bums need to go.
