Over the past few months, we've seen multiple instances where fast food restaurants have found themselves either understaffed or not staffed at all due to an apparent exodus of employees.
And while there are various reasons why those employees would no longer consider their jobs worth doing, that does leave chains with thousands of restaurants under their belts wondering how to deal with this "labor shortage."
Although immediate answers to this question seem few and far between, one project that McDonald's is testing out in Chicago could give us a glimpse into the future of drive-thru orders.
