A guy walks through a mall asking how all of the businesses are making money. He believes it's all fake.

The thing that catches my thoughts is how much of the world is fake. Like this mall exists, but no one knows how it makes money. There shouldn't be a way for it to work out. We have a dead Internet theory, but what if much of reality is just like that, and the internet is where it's easiest to spot?
There are all kinds of metrics involved in retail stores. These things are typically dealt with in some degrees or specific economy-based educational courses.
Also, some retail stores end up taking a ton of packaged merchandise to the postal office at the end of the day, which they sold online.
Another thing too is that given how fake and gay the products at some online retailers like Amazon can be, it's a safer bet to go through a reputable retail store for certain kinds of items.
And like you said, a lot of these retail stores have already been adopting various order/delivery methods, which covers some of the extra convenience customers might want.
