One way to allay possible suspicions that you're a pilot would be to turn up with some bird who looks as though she's worth a night stop. Pilots in Maun seem always to be complaining about three things; no work, nothing with whom to pass the long nights and a hangover, something consequent no doubt upon the previous sad condition. Arrive with something scrumptious and no one will think for a single second that you might be a flight hazard.
