I'm driving near my home. I see some teenagers hanging out alone by a river. My immediate thought: "what are they up to..." as I'm used to shenanigans in SF. As I drive by I take a look and...they're fishing...fishing! "Well..." I say to myself, "...what a wholesome activity...good for them"
People may not talk to you about politics anymore, but anything else - work, kids, cars - is a fair game.
At any rate, I live in the bay area now and I very rarely encounter issues with un-friendliness in the contexts mentioned in this thread. The lack of effusive friendliness that I do encounter for the most part is cultural. Which makes sense, as the bay area is extremely diverse culturally.
I want a burger. I Think about the unmotivated and borderline rude cashier I would have to deal with.
Then the smiling and upbeat workers at Chick-fil-A. Well guess it’s chicken yet again.
I still go to Chick-fil-A because the sandwiches are good, but I feel guilty about it afterwards.
So, yeah, I'm with treeman79. I think you're projecting.
