We live in a fast food instant gratification society. Customers just seem to have no patience at every level. Who is not complaining about lines at any location.  

The touch screen wait staff is a conundrum: customers get unhappy when the staff has not waited on them within seconds of being seated; while complaining the computer assisted ordering removes the personal touch.  Perhaps this should be looked at in terms of what you are willing to pay. The drive up window fast food places tend to have lower prices while restaurants have higher prices for similar items.  Low end restaurants are competing against burger joints for customers. At the other end of the spectrum are the customers who truly wants chef prepared dining and not a precooked frozen delight.   

Food serves job have been declining every since MacDonald's and Subway have had the audacity to call themselves restaurants.  Some of these joints are even returning to the auto-mat days where a robot will cook the items.
