About subtle - or not so sublte cultural differences

This has been bugging me for weeks so now I'm throwing it out there.  If you are a recent arrival in another country or even if you've been living in a foreign country for years are there things that you just expect to obtain without use of the internet, local foods that you grew up with, the school system, the rubbish collection system, transport, sales tax, healthcare, things that shouldn't broadside you but do?

In my case I've been trying to drink less soda.  Easy, I thought, I can still have fizzy drinks, I'll just buy a sodastream and drink fizzy squash all summer. Buying the sodastream wasn't a problem.  Squash however was.  The squash I am referring too isn't the sport, or the vegetable it is a  fruity concentrate (usually orange) that you dilute with water to make a drink.

It's a staple in England, in fact we never had coke or pepsi in the house that's why I still have teeth.

None of the supermarkets had it, they had plenty of fruit juice, crystal light (which sounded like a plan until I read the ingredients) pre-mixed drinks, and of course the dreaded coke aisle but while fruit juice kind of works, it's not squash.  So off  I went to Whole Foods (or whole paycheck as my friends call it) juices galore but no squash.  Luckily for me we have the London Market and the Old Dutch Store in Utah, both of whom sell squash in various flavours but because it is imported it is not cheap.


So here's what I want to know.  Is this a Utah thing or a whole of America thing.

5/16 Several suggestions from fb and e-mail for Mio - a liquid water enhancer (Is there a solid water enhancer?)  I checked it out and having read the back and not even found the strawberry flavouring in the strawberry watermelon variety five ingredients in I think I'll pass.  Thanks for the suggestions though - oh and apparently in the US they don't call it squash they call it cordial.  I stand corrected.

7/13 Torino make syrups which you can use to flavour Italian sodas, my current favourite is the sugar free vanilla.  A tiny amount goes a long way.
