Well, I’d feel uncomfortable eating there - they’d probably bring out English food instead of steak...
I lived and worked in the UK for several years. My son was born there and is a dual national of the USA and the UK. I considered the UK my second nation of allegiance. I would have fought for the UK in war. I am to old to fight today but if not I would not fight for the UK. The UK is no longer a free nation worthy of fighting for.
