I think that was his real work on restaurants and bars DVD. Great Advice, but like he said, don't scare the hell out of people with the noise if you're doing walk-around.
I've found that there is a large difference between impressing the audience, and entertaining them. To use an example from my life, The friend who could do a back-flip was great at parties, but the friend who was hilarious and a people person made everyone's night a little better. While both can be equally inspiring, i would go for the latter friend.
I can do springs and card flourishes all day, That will definitely impress people. But not as much as a simple card trick, like a Monte or ACR, when presented correctly. I had exposure to the two sides of this at a graduation party I was at. I was invited to perform magic for a table of parents and adults, so I walked over, and did some material; routines that I normally perform at the restaurant. Reactions were great, final trick went off wonderfully with a final climax, the crowd was thoroughly entertained, and all was well and good.
Later that same party, I was fiddling around with cards, practicing some Sybil or Molecule variation (I am by no means a very good flourisher, but I have a few up my sleeve.) And a girl was very transfixed by the flourishes, and i asked her if she wanted to see something, and she said "No, I just like watching you shuffle". Luckily her boyfriend, a friend of mine, wanted to see something, so I jazzed from there.
i learned from this, that generally I prefer structured magic routines for lay audiences to be the most memorable, and flourishes to be a good way to get peoples attention ( or a fire wallet in Draven's case). Though for some people, Flourishes are enough to entertain them.
