I like travelling in countries where you instantly turn into a multi millionaire. You hand out just one 100 US$ bill to the money changer and find yourself loaded with a pile of notes in local currency. The flip side of the coin is, that in the beginning you will always end up in sweat when you receive the first multi digit bill for a simple lunch and then find out that you will lose your millionaire status far too soon again, if you don’t schedule a next appointment with another money changer.
