Who's the idiot who designed the checkout ATM-card readers at Shaw's?

Spatch details just how bad these things are:

... I'm not sure who designed the checkout points of purchase at Shaw's supermarkets, but I'm willing to bet it was a friend of the lowest bidder who designed the Charlie Card machines. There are so many stupid little user interface problems with things that it's amazing any actual currency-based commerce is conducted successfully there on a daily basis. I think we'd be much better off going back to the bartering system, only I'd hate to be out of chickens when I need to buy more toilet paper. ...

Oh, yes, he also wishes to have a word with the idiot who designed the self-checkout lanes at Shaw's.
