This may be the future for fast food restaurants.  This design actually takes up less space per acer so a company like Yum Brands buying a couple acers can squeeze in an extra brand to fast food row.

The extra spaces to wait allow the kitchen to have items that, gasp, take three minutes to cook and prepare, while actually increase overall speed and through put by a bit over current drive thrus with just a single lane that focus on speed and speed alone.

It’s not clear if KFC and Yum Brands actually plan to roll out the above concept, but it is now a strong interest within the industry as people might not want to sit inside for years to come, and they need to find a way to increase the number of customers they can serve while getting back to the expanded menus they once relied upon to get large enough groups of people to pick their brand over another.
