The flight on an “Royal Air Maroc” plane from Banjul to Conakry was short and comfortable. Well, as comfortable as it gets, leaving in the middle of the night and arriving in the wee hours at Conakry airport. Yes, we had our visas, didn’t have any duty-free items over the limit. So, our expectation was to clear the administrative wall swiftly upon arrival. Well, almost… Just before exit to the luggage belt, we spotted a lady in a nurse uniform, who checked the yellow-fever certificate of all arriving passengers. This was fine with me, since I had the required document. But Evgeny whispered to me that he had no such certificate.
