Nor did I said they were, rather Switzerland, Norway and others (too lazy to search which ones I still miss) governments, managed to negotiate their position with EU to their best interests.
It's not neccissarily "their best interest" for one as there is no objective "best."
A key difference is that in Norway and Switzerland the "political elite" is pro-European and often wants closer ties up to joining, in UK however the brexit is the culmination of a decades long "RU/Europe/Brussels is evil" campaign and the British government gives little reason for the EU to believe in good reason for their negotiations.
