People in the US get thanked for “their business”; in the UK, they are thanked for “their custom”.
Whereas Americans have “coupons” and “gift certificates”, in the UK they have “vouchers” for both cases.
The US has “Business Hours”, and the UK has “Opening Times”.
The United States has “electricity”, but in the UK it’s “the electrics” or “mains”. Voltage here is actually 230V +/- a percentage. (Thankfully, my 240V transformers work just fine.)
“Post codes” in the UK gave way to “Zip codes” in the US.
Phone numbers in country in the UK require that you dial a “0” which is ommitted in the long distance version of the number. For instance, in the UK, you dial 07-9…, whereas outside you reach that person with +44 79…. In the US, you always dial the full number: +1 91….
Coins are worthwhile here in the UK, at least at 50p or higher. I quite like pound coins, and even the 2 pound coin can be useful as payment. They’re actually worth something, especially when compared with their worth in dollars. The bills here are different sizes and colours depending on their worth, with bigger bills worth more.
Time is basically always 24 hour time, and it’s DD/MM/YYYY here. (Of course, it should be YYYYMMDD everywhere, but good luck convincing people of that.)
Trains may all be “running well” in the US. In the UK, a “good service is running on all lines”.
Detergents are “bio” or “non-bio” in the UK, which means … detergent with biological enzymes v. detergent without them.
You can buy hard alcohol, or “spirits” in the UK, in the grocery store. In a UK grocery store you can also buy “Brown Sauce” (which is like steak sauce but slightly different) as well as things like Marmite (and you either love that or you hate it). (I love it.)
“Candy” are “Sweets” and they’re so much better here.
They still don’t refrigerate eggs here. That just weirds me right out. 😉
