Hey Blunt, good to read you again. I was beginning to think that you may have joined the Navy, eh?
Just My Opinion:
If this meeting is true, it is very suspicious.
It is indeed strange that for some reason, meals seem to be the settings for betrayals.
In the Christian faith, the sacred Last Supper was the venue for the ultimate betrayal. It is written that Jesus informed his disciples during the Last Supper that one of them will betray him, and then privately confronted his betrayer Judas, and admonished him "What you are about to do, do quickly."
In the fictional world of "The Godfather," when gangster Michael Corleone was about to betray his "truce" with gangster counterpart Virgil Sollozzo, they were dinning together at Louis' Restaurant in the Bronx. Corleone intended to go into a bathroom to retrieve a pistol with which he expected to shoot Sollozzo. Before excusing himself to get the gun, Corleone told Sollozzo "I have to go to the bathroom."
Picking up on "The Godfather" theme, during the purported meeting you cite, do you not think it possible that the respective party faithful, as well as the Lancaster residents, were betrayed, and in that speculative regard, all of the actors perhaps said "Piss on them?"
