HELLO PARANOIA! HOW ARE YOU?!
I'm currently in Barcelona for the 2nd time in my life. Still one of my favorite cities I've ever visited and without even really knowing it previously, I think it might be because Barcelona is testing out these "superblocks" to bring back space to people rather than cars.
I have never heard of this "theory" but I guess it makes sense that if you send a small gift (food or toy) with your broken electronics, maybe somebody will be happy about it and rush your repair service through. I'm skeptical, mainly because this piece is sponsored by Swedish Fish.
