I don't know where this man got his information from, but it's quite evident that he's not a pu-erh drinker. He gives me the impression of someone who is very good at reading a teleprompter and being able to convey a sense of spontaneity; a good actor, in other words. It's evident also that the video is catered towards an audience that knows nothing about pu-erh, "now, you've probably never seen a beautiful pu-erh cake, or a tea cake for that matter..." How does he get away with this? Probably because the average person walking into his store knows nothing about pu-erh. So this the form that deception takes: a charming sort of chap, clean, well organized tea containers, and soothing light jazz. Interestingly, lots of people on Youtube seem to know much more about pu-erh than he does, and undermines his authority through their comments and the 'dislike' function.
This commenter makes a pretty good case:
"How could he get such an old Pu'er which not even the most enthusiastic tea lovers in China can find when he doesn't even know how to brew the tea. That's live (sic) giving a drunk hobo a bottle of the worlds (sic) most expensive wine. Doesn't happen."
It's pretty startling how misinformed someone who owns a tea store can be.
