No bugger'll eat 'em
I've never seen TUC Cheese Sandwiches anywhere outside a donation session: does Jacobs sell them to anyone except the National Blood Service? (I'd give you a link, but they barely seem to exist on the Web...)
And even so, I was the only one who disturbed the nearly-arranged pyramid of 'em. Everyone else was tucking into the bourbon creams, shortbreads, and jam rings.
