Maybe what AC is really thinking would be making a pass of the BOB cart through the J cabin "for those customers who may wish a choice other than that is being served or who wish additional sustenance."

After all, some J meals/snacks are so downright WEIRD (I think of the pancake-syrup-asparagus bowl) and most are no so MINGY-small, that there indeed would be a market.

Sad thing is that I have almost always found that when the J class FA sees you don't want either selection, or left it mostly untouched or didn't feel satisfied with your 3 oz chicken, she will try to get something from BOB at no cost for you. This, presumably, would change if the new policy, suggested above as a possibility, were adopted. "Oh Sir, how awful you didn't enjoy your asparagus with syrup; give me $5 and let me see what I can find for you to complete your J-class experience." LOL ? maybe, maybe not.
