Well my Truro prawn butty was an M&S Best Ever. I was just about to eat the second half of it when the gull swooped. It didn't touch me at all and it removed the whole half of sandwich in one piece and flew off with it, no knocking it to the ground or anything. I was filled with both admiration and hatred simultaneously. That was over two quid's worth of butty, that was. I did benefit in the end (though not fiscally) because I nipped back into Marks and bought another one, so my lunch was 1.5 times bigger than it should have been. Damn fine sandwiches, those.
