I can understand those mixing are not the ones that made the decision but is it too much to ask for a little notice on the product page? Last I read in these threads was special requests on juice not offered is a no go anymore. IIRC Lemon Cake was one that people were getting and they put a stop to it.
Just call him and ask about it. Guessing at what might happen doesn't help you. Maybe the result will be good. Or maybe you'll be disappointed -- but you already are, so what do you have to lose?
