I take objection at this. The problem with this variation in grain is that it causes lack of clarity in exact quantities, which we all know is something crucial in photography.
So in any further discussion, I expect that if people think of saying "take this with a grain of salt", they will do the RIGHT thing and instead say:
* Take this with (X number) grains of salt of (Y) brand
* Take this with (X) milligrams of salt
Please also state if kosher or not, and which anti-caking agents may be present.
We really need to put a stop to this madness.
