An InstaPundit guest commentary on the story suggests there's increasing complexity aggravated by decreased competence of the help.
I own a fast food restaurant and the biggest reason service has slowed (other than the growing incompetence of the workforce) is that we are all running our businesses with way fewer employees. We used to have 23 total employees, we now have 9. We used to run a lunch rush with anywhere from 6 to 8 people we now do it with 4.The owner's complaint lays off a lot of the blame for the incompetent help on public policy. I can't help but wonder whether there's insufficient help as a consequence of downsizing for its own sake.
While business has certainly decreased the biggest reason is probably labor cost. 7.25 dollars an hour for the current functionally illiterate, no work ethic, yet strangely full of so much self esteem they can’t take instruction teenage product of the public schools is also why staffing is low. We hire adults when we can but of course we pay them more thus high labor costs=fewer workers and slower service.
