This photo was taken many years
before the nationwide campaign of Mao Mai Kap, i.e.
‘Drunk - Don't Drive’, but when we stopped to ask for
directions, these friendly officers
insisted in drinking a couple of glasses (of whiskey!)
with them, before letting us continue on our way... by car!
They probably had their own idea of a campaign: Mao Mai Klab,
i.e. ‘[Get] Drunk - Don't Go Back [Home]’!
