Guys.
Some words of Wisdom, from a not so wise person.
When you travel, in any country, do not tell them you are from the U. S. A. or Europe. You can see the $$$ or Euros signs light up in their eyes if you do. Tell them you are from South Africa, New Zealand, Australia or maybe Canada.
Don't know why I never thought of it.
This was told to me by a Argentinian waiter last night.
