As someone with extensive UK sandwich experience, and extensive experience of being victim to sandwiches in the article, bad UK train station sandwiches win hands-down.

If you thought the bread was bad, the bread of the Lawson, 7-11, FamilyMart et al is far worse: Anemic, textureless, tasteless. I have no idea how the author could consider 'chewy' as an adjectivein describing it.

Fillings are an odd affair. Personally I prefer jam over an out of season strawberry. Fillings are also nothing as appetising as mentioned in the article. A sliver of tasteless ham, trimmed exactly to be on price target with perhaps one half leaf of iceberg lettuce. The port cutlet option nothing like mentioned, more like a few lumps of mainly breadcrumb, the off piece of meat.

Hitting a very narrow price range is what these sandwiches are all about. A very very narrow price band. This in true end to end supply chain, and is what Japanese convenience stores Excel at. No produce is on the shelves for a few hours. The microwave rice and noodle dishes are similarly precisely engineered. That there are three and three quarter mushrooms in your dish is no rounding error, that's the exact amount there's supposed to be based on all the costs and associated costs of three and three quarter mushrooms.

Saviour your decidedly mediocre UK train station sandwich. You could have far worse. You could have a Lawson or 7-11 one.

The triangle sandwich of the UK high street is its own unique thing. It’s not particularly good, but it is culturally distinct. I have a soft spot for them. Tuna and sweetcorn; cheese and pickle: these are cultural artifacts.

A kiosk at the railway station in Germany will serve you an objectively good sandwich. Why doesn’t someone globalize the EU railway kiosk?

eh. Seem on a par, to me. per jnsie's comment elsewhere on this page, perhaps it's just England / the mainland that has bad ones, they're good north and south of the border in Ireland.
