I wouldn't call him "World's Best Bartender," as if tending bar were merely acrobatics. I once knew a bartender who had flair with a cocktail shaker, but it fell well short of showing off. The best bartenders are good company, first.
Reminds me how much I dislike Tom Cruise! I thought the flair scenes were more impressive than that in the movie, but it's nothing like the guy in the video. Maybe I'm confusing the movie scenes w/ competitions I've seen. And, now I can't get the song Kokomo out of my mind.
