Canadian shoppers are starting a new habit. After checking an item if it is a US product they return it to the shelf upside down and turn several more of the same item upside down so the next shopper knows to skip that product.

Haha omg, I thought I was the only one childishly doing that. My grocery store must be really on top of re-facing their shelves, because I’ve never come across any upside down US products.

The biggest hint something is American is when the shelf is fully stocked and there’s lots of items missing from the nearby brands.
