Have you ever been in a foreign country, holding their own currency and about to exit, then, you go to the duty free shops in departure lodge only to be informed that "we do not accept xxx currency" we accept only Usd.
at this point you just realise you are holding 'monkeys' in your pocket.
Am thirsty @Addis airport, I have loads of Birrs in my pocket and I cannot buy myself a drink.
Is it that this countries do not apptove their own currency or there is something I am missing?.
