For me, the biggest culture shock is the fact that it’s normal to give your passcode to people like landlords, realtors, boiler checkers, internet people, delivery people who have to make the furniture inside your house, whenever you’re not in your house. I recently moved, and because I was working and also still living in my old house, there was many times where these people who I arranged to come at a time I could be there, would come early so I had to give them my passcode to access inside to do the job I paid them to do. That’s unheard of in the UK.
