Actually, this might be a genuine movie. It looks very much like one of those "health and safety" flicks put out by the RACD (British Army chaplains, among other names) warning us hapless sods about the dangers of drinking in Kenyan bars where the beer is/was 18% proof. The strings were to help a worse-for wear soldier to remain standing until the RMPs (red caps) arrived. "Nahthenwasallthis'ere?"
