Yes @Itsalonghaul it’s a postcode lottery. I can see how an island would be very different to the Basque Country - I have a holiday home on one and yes - outside of tourist season no hay nada . The summer season starts in 3 months, I thought you might have seen a different date, as for now Brits can’t enter Spain 
Cafe owners are not more important than the elderly- can you link where I said that? I said that now they have done the over 80s they were doing younger front facing workers at the same time as doing the over 60s. (From today that’s stopped). In fact they hadn’t yet done supermarket cashiers, they were on the list. They’d done police, teachers, dentists, carers etc.
So if your friends in their 40s were at more risk due to their jobs they would get it sooner than their friends who worked from home, for example. I think that’s a good thing, it acknowledges the additional risk faced by people who do public facing jobs and wrt cafe owners, who have suffered more than anyone due to a fairly pathetic furlough system, gives them a fighting chance at survival. It’s also a clever move as it keeps people meeting on outdoor disinfected terraces with distanced tables and maximum group sizes as opposed to furtively inside their homes.
We have had our third wave. I think you’re referring to the fourth wave which is starting now. It’s scary of course but preliminary figures have shown the hospital death rate down as well as the average age for deaths and no care home COVID deaths - ie the vaccine is working. It’s a vaccine versus virus race, but the variant isn’t getting the head start it had in Britain.
And if Spain really was so eager to get tourist money in, the Easter holidays would have been the chance to allow richer Spaniards to flock to the coasts as usual. They didn’t - to my own personal frustration- because they weren’t ready. It’s important yes - but it isn’t the be all and end all. Also, they are a big champion of vaccine passports and you even need to show a pcr to cross in from France now - they’re not going to have a virus free for all.
