At Spago on a Saturday night a while back Wolfgang Puck went to just a few tables to say hello and make sure everything was good. The only comment from the British couple next to us was something minor like they needed a fork or a water refill.

They were surprised when we got his autograph and a picture (what the heck, right). When they asked why we did that and we explained who he was they looked kind of embarrassed but later the woman walked over and they got his autograph too.
I really really admire him for doing this unlike Planet Hollywood or Emeril's where I bet you rarely ever see the owners.
