You know you're in Britain when the baguettes at the supermarket are hard enough to bludgeon somebody to death with. (As a part-Frenchie the quality of baguettes here really pisses me off. It's bread, not rocket science, and it's your whole job, bakers, learn how to make it.)
I remember milk in bags from my holiday with Canadian relatives many years ago. It has trickled over to some UK supermarkets and my Australian friend found it very strange when she visited a few months ago! I was like 'yeah but your supermarkets sell cans of coke with whiskey already in them!' You know you're in Australia when you don't have to mix your favourite soft drink and spirit, you just pour it out of a can.
Bwaaahaahaahaaaaa!!!!! You know you're in Australia when the local spirit sellers say "Fosters" doesn't come from there...
Nope it comes from down the road from me... or it did until they closed the Fed... The made it in the same place as Brown Ale...
You know when you're in america [and a few other place too tbh], when guns and violence are fine but the merest hint of nekkidness or 'bad' language and they all lose their minds...
You know you're in Australia when they charge you to use ATM's & to have a bank account.... You know you're in Australia when the internet speeds are from the dark ages. Just spent a year living there.
You know you're in Paris when there is fecal matter (a mixture of guano and dog **** mostly) scattered over every horizontal surface.
