Ringing for Attention at Restaurants?

In Food outshines service at Cetrella (SF Chronicle, October 15), Michael Bauer asks "What is it about empty restaurants that cultivates poor service? It seems like every time I go into a dining room with a sea of open tables, service is erratic".

I think there are more mistakes made in restaurants both in the kitchen and on the floor on lethargic evenings.
Compare it if you want to a band that cannot find its groove.
Rhythm is lacking.
Things do not flow...
