Chuks,
You give too little credence to the effect of blue curtains on armed robbers. It must be pretty daunting in that there has been no repeat of the event in Lagos. Perhaps they have gone south and gotten into kidnapping which seems to have a better payoff than an armed robbery of Bristow Pilots.
They must have had a mole in the office eavesdropping on the Mandarins rather than co-opting the barman who would have repeated our moans about the pay and allowances.
Since taking the vow of sobriety I have seen some snakes and spiders but not eaten any yet.
