Fast food is slowing down. 
A study released today by industry trade magazine QSR shows consumers are spending more time in the drive thru lane. Industry-leader McDonald's posted it's slowest-ever average wait time in the 15 year history of the study, coming in at 189 and a half seconds - nine seconds longer than the industry average. 
The reason seems to be menu-bloat - as food items get more complicated and varied the wait time is going up. Bigger menus are also affecting accuracy rates, which are going down.
Fastest average wait time ever was 116 seconds -- that was Wendy's back in 2003.  
Fast food restaurants typically do about 60 to 70% of their business in the drive thru lane.
