The laws governing obsructing pavements is a local Santiago del Teide council rule, passed 6 or 7 years ago but not enforced until a couple of weeks ago. (other counties may well have their own rules as well of course).
Basically anywhere which used to set out tables and chairs on what was essentially the pavement has had the local police (acting on instruction from the deputy Mayor) remove them and I believe fined. The full story can be found elsewhere - my previous post suggesting where on the internet it could be found was removed (no surprise there then) but it perhaps not sunny news for those invloved.
It is true that some bars/restaurants were taking up rather too much of the pavement for safety sake, but others like Bar Central which has had a few tables and chairs outside for more years than many would care to remember is one of the many places where you can no longer sit outside and whose takings will surely be affected.
Real question is why enforce a 7 year old ruling suddenly, and why now when many winter tourists to LG and PS are just arriving - a great way to pee regulars who enjoy a coffee and swift fag with the warmth of the sun on their faces.
Ahhh - council politics then
