So what's going on with Sal? Did Don believe his story, but think that he should have "befriended" the Lucky Strikes guy for business reasons? (That was my first interpretation.) Or did Don not believe his story, and think that Sal *did* get onto very good terms with the Lucky Strikes guy, or even that Sal hit on the Lucky Strikes guy himself?
Anyway, those last two eps were both depressing. Every single main character is a creep in Mad Men now.
