You speak like someone that has never met a British person never mind not having been to the UK.

The national dish of the UK is curry. There is curry everywhere.

I went to an Indian restaurant in America the women actually lived in the UK and we was chatting. I ordered a hot curry and it was fine.

But the Mexican woman behind me ordered a vindaloo which is a pretty standard dish in the UK. The Indian said "you had this before? Its very hot"

But "no but it's fine I'm Mexican. I can handle my heat"

"I'm just warning you it'svery hot. You sure you want it? Maybe you want x, y, z instead if you ve never had it"

"I'm good with heat. My family always makes things spicy"

Anyway it came and she ate less than 10% of it before getting it boxed up.
