Fast food had turned out isn’t quite as fast as it used to be. A new study finds that McDonald’s posted its slowest drive-through times since the service was first conducted 15 years ago. At McDonald’s, customers were spend on average 3 minutes and 9 seconds from the time they place their orders until they receive their food, as about ten seconds more than the industry average at a lot slower than a decade ago according to the study, which was commissioned by QSR, an industry trade publication. And McDonald’s wasn’t alone in slowing down, other chains also saw their drive-through performance slow down. Among the reasons for the slowing service, today there are more choices on the menu and products themselves are more complex and take longer to prepare. Speed, of course, is essential to the drive-through experience, and drive-throughs are hugely important to chains such as McDonald’s, Burger King and Tacobell. Usually, the drive-through accounts for 60 to 70 percent of all business that go through a fast food restaurant, notes Sam Ochers, editor of QSR. Of course, consumers also want their orders prepared correctly, and on that score, Ochers says accuracy is still really high.
