Taking my visits to the UK as a reference, the three above are not differences there.
In the 70’s my US born wife remarked on it being a country of skinny people - certainly not the case now.
Coffee shops are everywhere in the suburbs in the UK - the old shops that were grocers and butchers before supermarkets are now off-licenses (aka booze shops), nail/beauty salons and coffee shops. Even the three local garden centres (aka plant stores) near my parents house have attached coffee shops.
UK cars might not be quite as big as US ones, but lots of SUVs are being bought, and relative to the size of the roads, they are much bigger...:^)
So we'd scuttle in to some of these places where everybody would have their tea and snacks. Except for me because I don't drink tea or coffee.
In one place I asked if they had Coke, and was brusquely informed by the person behind the counter taking our orders (in her best Ann Robinson sneering voice) that WE DON'T DO COCA-COLA HERE!! I settled for a glass of water. Next time I'll ask for Vimto.
