Yeah Jerry, Benny did that a lot; give people names.  I think he had his own 'memory' system.  He couldn't (or didn't want to) remember your real name but he could always remember the name he 'assigned' you.  My story sounds a lot like yours ("buying, trading, dealing, haggling with Benny").  When I saw that video, it was like being transported back in time.  I can still hear his wife calling out "Bennnneeee" 

.  Ahhhh, you can take the boy out of Philly but you can't take Philly out of the boy.  Cintioli's ranks right up there with Pat's Steaks and the "Iggles" as a Philadelphia tradition.
