Even Corgis don't like British food: He probably expected bacon and instead it was some weird British sludge from a jar. And seriously, what's with the tagline "one either loves it or one hates it"? It's like you guys have pretty much given up. Even the companies making your food know it's a bad joke.
You would have to try marmite to understand but truly you do either love it or hate it, there is no in-between. It is yeast extract, I can't stand it but the wife likes it. The slogan has been 'you either love it or hate it's for as long as I can remember, possibly longer than I have been alive but it does well.
To be fair I love Marmite on toast with butter in much the same way I love a good cheese on toast, it's awesome. It's much less enjoyable on plain bread.
Brown sludge made from industrial by-products. Yum! The American equivalent is peanut butter, which is awesome and delicious. Nobody likes Marmite. Even the company that makes it basically acknowledges that they're selling you industrial waste in a jar. Apparently vegemite isn't much better:
Do you guys have jam or preserves over there? Here's what's in my fridge: Ingredients: Fresh apricots, corn syrup, sugar, pectin, citric acid. It's ground fruit with sugar and a natural thickener. No yeasty, salty industrial by-product nastiness. Sounds much more appealing than yeasty goo.
Peanut butter is OK on its own, but pair it up with jam or preserves, oh man, what a delicacy. That'd be a cheap breakfast, lunch, and dinner.
