I am the USC but I lived in London for awhile and I know I had the culture shock when I first got there and then had reverse culture shock when I returned

. Things I have to get my Irish Fiance use to:
- It is not Petrol - we call it Gas no matter how much you want it the other way. The American born kid making minimum wage behind the counter will not know what petrol is ;P
-It is the trunk and hood, not the boot and bonnet.
-Refills.
-European Large soda at fast food is a medium in the US.
-Sales tax paid at the register and not included in the displayed price.
-Lack of Chip and Pin, though he was use to it from the fact I used American cards in England and consistently had to tell them it wasn't chip and pin.
-If you don't go to your banks atm you will be charged a fee where as in the UK you can go to any bank ATM.
-Paying for bank accounts.
- Health care - though I am VERY LUCKY. I not only have free insurance at my job, I also get $45 in FSA every paycheck which means essentially they pay me to have health insurance. But this is extremely rare and I have never encountered it before. Adding my fiance when we get married will cause me to pay about $150 a month for insurance for him and this includes dental and vision.
-Holidays - I have already begun to enforce this with him. I am again very lucky as I get 13 sick days and currently 2 weeks vacation which will be raised to 3 and then 5, and my job will work with me on stuff. If I need to work overtime to make up for a day off they will let me. I can come in when I want and leave when I want as long as I get my hours. We also roll ours over and it NEVER goes away. It is SUPER rare and so not normal. As my boy says - I work at a holiday camp it seems. I love my job.
-The date writing which is a big one.
-Everything is bigger. Our one bedroom apartment now is bigger than the 3 bedroom flat we lived in in London. Our fridge is huge compared. Our kitchen is enormous compared.
-Needing a car. He doesn't have a license because the public transport in Europe is so good. Here he MUST have a car. It will be fun teaching him to drive on the "Correct" side of the road.

-Food Portions - though I did take him to TGIF in London so he can start prepping for the difference

-Clerks at the supermarket bagging your groceries. I was floored in London going to Tescos and having to do it myself. I was like what the hell. Oh and our clerks do not get to sit in comfy seats while ringing you up either.
-Capitalist corporation society - though my job is an exception, most in the US - your job is your life. You are expected to be on time. Even if you have 2 weeks paid vacation and 10 sick days, you will be lectured to and possibly let go if you take them all. We are a right to work society.
I could go on and on and on and on....
