Well, coffee shops and restaurants haven't quite figured out how to manipulate customers for maximum profit like social media has. They might play fast music to get people to eat quicker or put some pricey items on the menu to make everything else seem cheaper. But they haven't gone as far as placing MLM sellers next to lonely customers to pitch sales and making them come to the shop every week, or causing couples to break up so one starts drinking a lot out of stress and brings short-term profit.
