 After the beat up scene, Andreas states, "Well be seeing you next  Wednesday". All of the pyramid meetings take place on a Wednesday in  the story. The next meeting is on the Yacht. This is a direct  reference to John Landis and his frequent use of "See you next  Wednesday" in his movies. Also see "2001 Space Odyssey" where a  character says this to his family but is killed before ever seeing  them again.
