ELI5: Why does anywhere that serves breakfast stop serving breakfast after a certain time?

I don't get it.

Take your pick, the answer is any combination of this.

* kitchen space, need to keep prepped items for both breakfast and lunch/dinner at the same time.
* swap out equipment for breakfast and lunch/dinner
* kitchen staff levels
* customer demand 

For example McDonalds uses a grill for their breakfast, when switching to lunch/dinner, they use the same grill for hamburgers. There is usually only 1 cook, sometimes 2. So breakfast all day is difficult for them, but they are looking at a solution that would work at all McDonald's locations.
