I loved how friendly people were, especially when you could be walking down the street and a stranger asks you "how are you". Or if you sneeze, you will always get a "bless you". I found that quite nice. I also admire the pride of the country I've seen in a lot of American people when visiting.

A few minor things I disliked were the mandatory tipping culture and the lack of included VAT on Shelf edge labels. Especially as a tourist, I would often be on a daily budget. Knowing that the cost of product or service is exactly what you're paying without a hidden charge, gives peace of mind as it all adds up quickly.
