I heard from a 'good' source (Sauce) that the BE18 man used to carry a rather long, large stick - CASA Approved - so that in the unhappy event of one 'donk' not 'donking' - he could bash the stick around all the boxes/crates so causing the chickens to flap their cute little wings - in unison one would hope - thereby effectively causing an immediate decrease in the effective AUW....
Aw shucks, t'was the best I could do at short notice...
