I'm finding it difficult to think of a single country where you can fly to a
second country, but can't obtain that second country's money until you get
there, and where US dollars cannot be used in lieu.

The problem here is that I have sterling accounts in the UK from which I
can draw pounds without exchange commission. I also live most of the
time in the USA. Arriving back in the UK from the USA requires me to
find a cash dispenser. I'm amazed at the apologists here who claim this
is an unrealistic expectation.
