why do british and americans think sushi is posh food?

I really do like sushi, but I eat less of it than I used to.

Sushi, being fish, is becoming more and more expensive as we rape the seas of various fish types and species. People, myself included are more aware of this, so I've chosen to eat less of it.

I've had sushi in London. I haven't come across anyone thinking it was posh, though my Dad did say the restaurant bill was twice what it would be back home.
Maybe the price was posh?
Or the restaurant thinks of itself as posh?

Neither the dishes we were served, nor the people around us had any reason to indicate any posh-ness' to us..

Probably because it is a b!tch to make.

We are not skilled at making it and revere others who are.

Probably because we consider it to be "exotic", coupled with the fact that eating raw fish is something that is otherwise not done in our own cuisines. So, novelty.

They do? Sushi is just ... ordinary, I thought.

because they don't understand it

Not true.

its not that Great either found some once it was still fresh , but i was like meh

Probably because of the prices, it stinks from what I've noticed about it.

They eat junk a lot..
