I like it, just one thing to think about... what do you do when others want to exit the row? Of course moving it seems easy enough but you will have idiots that knock your corn all over the floor.

hmm...very keene of you. Never considered that. I guess it will just have to be moved for the moment, along with one's knees and feet.

I thought about it some more. Perhaps the holder could swing, inward and outward, thus preventing the knock overs and allowing you to bring it closer if desired.

Ah, even better. And possible if the cup holder frame is mostly uniform. And how about a tilting possibility? I can swing the bag around to myself, then tilt it to access the bottom of the bag/bucket. I like the way you think, bkeene. I invite you to my blog of ideas (www.sparkbugg.com) and would love your comments there as well.
