Once I got four, count 'em, four, in one order of six. Up one slot, we find Arby's. Arby's will never give you a gray nugget. Granted, that meat is white and tender, but it's not much when you consider the size of the entire chicken strip. Never have I once encountered a gray nugget while eating at either of these places.
Meat is always white and juicy.
Notice that the infernal gray nugget seems to be the sole province of McDonald's, a gigantic multinational corporation that simply has no excuse for that kind of sloppiness. The strips are tender and juicy, and what's more, they aren't battered as heavily. I find this to be a refreshing change. I'm not claiming to be a total authority on this, of course, but I think that this is the kind of stuff that everyone deep down knows.
