Interesting post that Jake.
I can speak from experience that when we came to UK, way back in November 2002, it really was a "re-entry schock" for me.
I hated it and found it extremely difficult to settle down.
Didn't like the food, or the prices. The people looked stressed and angry and their behaviour supported that impression. Most people were dressed so casually and dishevelled it appeared scruffy.
Nothing seemed to function or operate as it should. Shop staff sullen and unattentive. Customer service non-existent.
Fast food outlets dirty, tables not cleared and cleaned, floors dirty and spillages left to get trodden around and sure did.
Excessive yobbish behaviour and lack of visible police presence made 'going out' unpleasant.....
