Then of course I selfishly hope that at least my side is hurt the least

It's not just politeness though. Losing a lot of trade with the UK will hurt us too. Sure it will likely hurt them more than us but that ship has sailed, I prefer the best outcome from the current position. And yes, I do realise that a too 'lenient' deal could undermine the EU (which I do not want) and that contrary to the belief of some the negotiations are not just about trade.

And more practical it would cause a lot of headache at my work, we have British employees and (critical) suppliers, and it is if course a market for us but if they don't accept CE mark we're probably not going to sell anything there (being a fan of our product I'd say that's also a big loss for the UK of course).

I guess it was politeness that made me post it though but only because I felt it is polite to day at least something in topic
