Back in college, I remember waiting in a buffet line and there were, what I gathered to be, two of the cafeteria managers in front of me. They were chatting about the efficiency of buffet lines and one of them mentioned "It's well known that a buffet line with a server is 30% faster than a line with no server." Made total sense at the time because in a self service line, people have to: - stop - pick up the utensil - some people then take a while deciding which piece of food is the best - grab the food - put the utensil down and move on etc With a food server, it goes so much quicker if only because the server isn't waiting around to pick the best piece for you.
