I find that McDonald's, in particular, to always be a complete mess operationally.
That's a bit obtuse. Corporate has well-designed systems in place for all aspects of a restaurant's operation - if they're not being executed properly, then that's down to the management.
Of course, owners can tweak these as they see fit, but they are subject to operational reviews multiple times a year.
