In reality, the chain probably isn’t suggesting that people eat its chicken nuggets every three hours and is merely using it as a suggestion---or just as a form of marketing (it apparently worked because several stories on the nuggets went viral).
Nevertheless, it would be hard to recommend anyone eating grilled chicken approximately four or five times per day. It’s even more strange that it was printed on the side of a take-out bag that has fast food items like waffle fries, fried chicken, and sugar-loaded sauce.
