When I lived in S. Calif, I kept asking myself, “Are these people all on drugs?” They have the slowest cashiers I have ever seen, and they’ll stop checking your order to show someone else their new shoes & then discuss the great sale and price they paid, while you’re just standing there.
Cashiers here are usually quick (unless it’s a man), polite, and you’re always greeted asked “How are you?” “Were you able to find everything you needed?” and at the end of ringing up your groceries “Do you need any stamps or ice?” Your change is always counted. Then you’re asked if you need any help out to your car.
I guess I’m spoiled.
Revisit “My cousin Vinny” wherein Steve Mrtin (Vinny) does an impeccable illustration of a NYer’s reaction to friendly So Cal niceness.
S. Cali is akin to Queensland in Australia (in my experience). Some (many) in Sydney for example tend to joke that Queenslanders still live in the 70s, and are behind times.. real slow, sunshine state (not golden state), surfing dudes, you know.. must be the weather & humidity!
Personally, I like Queensland & Queenslanders. They are friendly, it is a dream driving in Brisbane versus nightmare traffic especially in Sydney for example, and mentality wise Queensland seems more like a big country town - polite, down-to-earth, and personable. Queensland has more gorgeous beaches & crystal clear water than Sydney, Melbourne, or even Perth. Not to mention abundant, unique & excellent quality seafood. Actually it is quite idyllic living.
But, overall, I’d say Australians are equally friendly & helpful as Americans. Europeans are a different story.
