Such an irritating airport to get around. Terrible signage. Confusing unintelligible announcements. Our flight was allegedly leaving from terminal 1. After lugging all our stuff there we were told to go to terminal 3 to drop our bags. Then after that walk to the international terminal to get the flight. At security no plastic bags being given out. No obvious signs to say what fluids are permitted. Nothing to say I had to put a laptop in its own tray and everything else in another. Just a rude guard telling me like I should know already. Gave me no help just watched me as I held up the queue and flapped around. At the gate no toilets. No retail. Walked miles to find food when we did was 11 dollars for a pathetic sandwich. San Francisco is an excellent city full of great people and great design. How did they get it so wrong at SFO?
