SFO ATC...
Been to Ksfo numerous times.
I have rarely seen more dangerous ATC controllers anywhere in the world than in Sfo.
Speaking fast is considered to be a sign of efficiency. Speaking faster in English with a pilot for whom English is obviously a second or even a third language is considered to be super efficiency, bordering onto things in cheek humour for their colleagues.
What business does a controller have, to clear a heavy jet for a 'visual approach' into a fully controlled airfield where ALL landing aids are available.
That too, very frequently when simultaneous parallel ops are in progress.
Besides absolution of responsibility.
Notwithstanding the obvious lack of certain flying skills, I would have the ATC equally share the causal blame. And therefore have them partake equally in the cure.
