Synchronistic Event #27

Yesterday I met my mother for lunch at our favorite Japanese restaurant, Noshi Sushi.  We were seated at a table from which the working side of the servers' station was visible, which includes a set of pigeonholes (for keeping checks separate, I guess).  As is my habit, I automatically started counting the pigeonholes.  There were 20, but just as I checked off 16 I heard the old lady at the next table say "...sixteen" to her companion.
