This is all true. You also can ask for ice with your coke. This will endear you with the wait staff as they can not resist snickering and muttering “American ..”
In the US I always had to specifically ask to not have ice in my drinks.
That was one thing I could never wrap my head around.
The other thing was the extreme use of AC. I can understand AC to an extent, but they were making it so cold I had to bring extra clothes just to go in the supermarket for example - what the heck?!
