In general, most of us who answer (and I am no pro cook anymore) try to gently, or directly let the person asking know that they are going down the wrong path if they are suggesting they are going to charge. There are many times i have let a question go, because I didn't like the posters intentions. If a person comes on and starts talking about undercutting professionals, and they respond negatively to the first one or two suggestions about doing it right, I will let it go.
I do try to help, and also when needed, I come here to ask, for confirmation and/or guidance on larger cooks.
me: I don't drink anymore
Yelonutz: me either, but, then again, I don't drink any less
