There's always a low grade cheesesteak war going on along the eastern seaboard (believe me, don't even engage a Philadelphian in this discussion, it'll go on for hours and pull in half the neighbourhood) a good part of which is size. Size is very important to Americans. I feel for American womanhood, who upon engaging in bedroom activities with the man of their choice, are forever cursed with the knowledge that they've held a sandwich far bigger than that earlier in the day. Even American men, when they look down, must think the same, that that's no sandwich.
Anyway, some cheesesteaks are now so big that they can be mistaken for a small nuclear submarine. Admittedly, one after a bizarre Cheez Whiz accident. And no, I'm not saying anything bad about Cheez Whiz because I love processed cheese food products. Plus I think the cold war would have been a lot more interesting if they'd swapped nuclear weapons for food products. Imagine it the Americans had coated Moscow in Cheez Whiz. The Russians could have retaliated by turning the Potomac rubescent with a carefully deployed burst of borscht followed up by a cabbage-related offensive up the coast. Before you know it, Twinkies would have been falling from Leningrad to Volgograd and Hostess Cakes would have been bigger than Lockheed Martin.
But yes, British supermarket sandwiches. If there's any meal that epitomises disappointment, it's there, on the shelves of a high street. It's no wonder Pret and the like get away with £5 sandwiches when the alternative is a couple of limp slices of bread uneasily caressing a minimal amount of filling that's been embedded in a tomb of glutinous mayonnaise for about seven days. The whole thing tastes of sticky nothing enlivened by occasional cryptic changes in texture.
