I just crossed the border from Serbia to the Republic of Macedonia and was surprised that the currency exchange booth on the Macedonian side accepted Euros but not Serbian dinar.
Generally I've found even in places that are not very friendly at least at the border it's possible to exchange money if not elsewhere.
Does this mean that I won't be able to change my Serbian money for Macedonian money? I didn't expect Macedonia to be on unfriendly terms with Serbia.
