Can you imagine a parody of this ad with gongfu cha instead of a tea bag?! I think that the joke could be built around the fact that customers get free hot water refill in most places! A gongfu cha customer would keep on calling the waiter to bring more hot water for over 10 brews (of puerh, for instance)!
I live in Taiwan since 1996 and have been studying tea with Teaparker. He's a worldwide tea expert and author of over 30 tea books. The study of tea isn't just theoretical, but it's also rooted in daily practice. It's a path of continuous improvement. As my brewing technique improves I get access to better teas and better accessories. These things go hand in hand. My blog documents my learning since 2004. And I have set up an online tea boutique with my selection of top quality teas, accessories and tea culture.
