A grocery store already manipulates consumers though, e.g. they put the milk at the very back so you have to walk through the store which increases the chances you'll buy something else.
Part of this is why I prefer to shop at Business Costco for a lot of things. While I am sure a similar tactic is being done, it is being aimed at other businesses - and since I am not a business, it doesn't affect me as much (though it does confuse me why they place certain things side by side - but if you think about it like what businesses are looking for and the type of business - then the placements make more sense).
