Here it is.
"All 125 volt, single phase, 15- and 20 ampere receptacles installed in the locations specified in (1), (2), or (3) shall have ground fault circuit interrupter protection for personnel:
(3) Kitchens "
I realize restaurant kitchens have a lot of circuits, but many of them still won't require GFI protection. I think that this requirement for GFI protection is reasonable, never could understand why a commercial kitchen was less dangerous than a residential kitchen, especially with all that conductive stainless steel.
Few things are harder to put up with than the annoyance of a good example.
