Ex-industry gossip
It seems to me that Berlitz aim to be the Ivy League of the English Conversation world -- the place where you go when you're so serious about learning English that you're even wearing a suit. They don't have celebrities in their ads, they brag about rejecting the vast majority of teacher applications they get, and all that jazz.
But then they carefully put that aside and proceed to seltzer themselves in the face by using their on-train advertising time to teach passengers the phrase "working hard or hardly working?"
Seriously, Berlitz. What's next? "Hot enough for ya"? "I just flew in from Hong Kong -- and boy, are my arms tired!", perhaps? Maybe we can dig back even further and teach the people about "Oh, you kid!"

"Take my English class -- please!"
