I think it’s more complex for chippies. Fish and chips was meant to be a cheap treat, that’s why it has such a strong working class heritage behind it. So the price rise makes it untenable in a way that may not affect other takeaways. Like, if I’m going to pay £20 for some fish and chips, I might as well have a Chinese. It’s a cultural thing.

Hehe I am left-handed and live alone but I’ve noticed guests hesitate when they open my cutlery drawer. Spoons aren’t such an issue, but there’s a little element of danger when a right-handed person goes to retrieve a knife 🤣 (My chopping knives are arranged horizontally like OP’s spoons.)
