Often, when diplomats/expats of one form or another in Abuja's 2 or 3-year stint is up, they advertise on the Abuja expats list, selling the detritus they've picked up during their time. Its quite hilarious to read what they sell and how they sell it. Stuff worth 30 quid down Ikea is sold second-hand for more than it was bought for. Mobile phones, cars, sofas - all are advertised at more than their brand new value without a soupcon of irony. Its basic economics at work on one level: the unconscious exploitation of scarcity by homo rationalis. On another, its just oyinbos being stingy. I heard this evening that one expat recently sold a half-drunk bottle of whisky - for forex mind you (not naira). Haba.
