I like to think about things in terms of labor input. Like if you go to a restaurant and pay $15 for a plate of pancakes then the entire labor that goes into that is less than an hour.
And that's for everything. Farmer growing wheat/chickens, cook making batter + cooking, syrup, banana growing, spices, clean up, waiter, etc.
Realistically if we're talking about just the restaurant bit there can only be a few dollars of labor and therefore maybe like 5 minutes of labor at most. Only way to achieve that is through scale.
