You just know you're in Africa
When:
You're on a VVIP charter in Nigeria from your base in the South to pick up a "principal" in the far North East.
En route you stop at a mid belt airport for fuel (having contacted them previously to confirm availability).
Having done the usual dance with Customs, Immigration and the SSS you walk back towards your aircraft and watch a diesel tanker draw up. Just in time you prevent the rather indignant bowser operator refuelling.
When you ask the Airport Manager to explain why he told you there was fuel he looks surprised, asks you "What is your problem ?" and tells you they do !
