In general, if I have a recipe someone wants, I give it to them, with the caveat that I measure rarely, and poorly, so it is all estimates. Now, if I had a business, say a rub business, then I would just politely decline, saying I normally share recipes, but, this is my business and I simply can't give that recipe away. But to lie, in a purposeful way, to misdirect someones efforts, that rubs me wrong.
I used to see it in fishing all the time, someone asking about what someone is using, and the more experienced fisherman lying about the fly or bait he is using.
I'm feeling bearish, and I'm packing a Wusthof Grand Brisket slicer from MABA
