Bought a cold sandwich at a quick-service place in England.
There's your problem. This one has a certain appeal, though. I'd pay eight pounds just to be spared the usual pile of cucumber slices, old egg, and obscene quantity of mayonnaise.
I too am impressed they managed to not include tomatoe, avocado, bacon, lettuce, or a sauce of any sort, while simultaneously not bothering to interlace the cheese between the meat for a more interesting texture profile.
