I'm pretty sure there is not. There was once an idiotic discussion on this forum a couple years ago, where some foolish people were arguing that water wasn't a safety issue with regard to electricity, because "most" modern plumbing is plastic. One of the underlying ideas in the electrical codes is that things can often change, and the code tries to make things safer by covering whatever might be there. The fact that plastic doesn't conduct electricity really doesn't enter into it. It's even possible that electricity could be conducted through running water down through your plastic pipes to a point where it touches metal and ground.

If you think about it, every metallic appliance in your kitchen (large or small) is a pretty good ground (assuming an EGC and 3 prong plug). You get caught between a hot leg and almost any metallic surface in the kitchen, and you are talking about a phase to ground short with you in the center of it.

It certainly does matter. This is why GFCI are required in bathrooms, garages and exterior locations as well - potential wet areas. There are no "metallic appliances" expected to be on your back deck or bathroom, for example. Now it just might be that if there were some strange room in houses that had a lot of "metallic appliances" but no wet area for some reason, that the code would require a GFCI there too, but since there is no such thing, the "raison d'etre" for GFCI is the presence of water. Water is a pretty decent conductor of electricity, and that's the bottom line w.r.t. the code.
The earlier post inferred that GFI protection was only required near a water source in the kitchen. The requirements are for ALL countertop receptacles to be GFI protected. Therefore the statement that the sink doesn't matter.

This is my solution to remember that there are multiple circuits in one box:

The height of fashion! I'm sure all the women of the house will love that. Wouldn't it make more sense to put that inside the box?

I write the breaker #s on the inside of the cover plates. Not many home owners like them on the outside.
