As you know, there are some differences in spoken English in the USA compared to the UK, better known as US-English.
I remember the first time I came to LA back in 2003. I was at a bar with friends and needed to use the toilet. I walked around and saw a sign “Restroom”. I had no idea what that was at that time and didn’t see any signs with ‘Toilet’, so I asked the bar staff where they were. They pointed me in the direction of the restroom. That’s when I figured out what restroom meant.
Aside from that, here’s a few things I’ve got used to saying on this side of the Atlantic.
Downtown (city center)
Parking lot (car park)
I’m just thankful I don’t have to use US-English in my design documentations.
