Ban? NO. Educate? yes! I don't like the notion that a judge would take a very tiny bite that was not enough to judge because he/she didn't really like chicken. As long as it was enought to taste the meat and sauce, then it is OK. I really would not want a 9 from a judge who didn't even get a big enough bite to taste what I had turned in.
I don't give a hoot what they take home, but at least take a big enough bite to judge. Most judges I have talked to take what they are doing very seriously because they understand what is on the line.
