The food portion comment is also a pet peeve of Mrs.JimSea. The lack of world knowledge is common to both USA and Thailand where geography was not taught when she was in school. The traffic is very orderly and polite here in comparison to Thailand or Southeast Asia in total. Most of the other observations are dead on.
I’ve seen restaurants up-serving portion sizes (and prices) over the past decade. You ARE charged for what you are being served.
