Despite now having lived here for nearly 2.5 years, there are still some typically British things I do regularly, if not daily:
I still convert everything from Dollars into Pounds before deciding whether to spend any money!
I read a British Newspaper online every morning as soon as I log on, to check everything's ok at home & get news
I still start every single day with a hot mug of tea, usually PG Tips (which I have to buy online) or Earl Grey. But my hot tea intake doesn't stop there; when I get home from work I'll have another cuppa and usually another one during the evening. As well as hot traditional tea with milk, I also drink Green Tea and various flavoured tea's - still a tea addict and hubby is now also a convert to hot tea with milk and sugar!
I still regularly refer to the restroom as the 'loo' in private. I soon got out of the habit of asking for the loo in public, due to all the blank stares I encountered. But when I am at home or at a friends it's still 'I am just popping to the loo'!
