The enjoyment you may get out of talking to a sushi chef or similar is this mutual respect that if the chef wants to talk to you about software, you are the professional and you've spent your life perfecting it. When you speak to a sushi chef, you expect the same level of competence to go into his food. In other countries often when you go out to eat you don't even know the name of the restaurant, or even care... When you make plans to go there you reference the restaurant by the name of the chef that works there. "Hey, I heard Chef Baca is working at Roberta's Pizza Joint, we should go". When you go to a sushi bar, you expect the chef to give you your sushi exactly how it's meant to be eaten. You dont ask for a side of ranch, or ketchup, which is kind of like walking into an art gallery and asking the artist if he can add some more red brush strokes to his painting because you really prefer it that way.
As an artist, or a chef, I would kindly ask you to leave and take your bowl of ketchup on the side with you.
