To set the scene - imagine you're the only Brit in a multinational HQ environment - plenty of bizarre uniforms and customs at every turn. At some point some hatless foreigner salutes you (also hatless) with all the respect and smartness available to a foreign army. Do you: a. Brace up in the safe and certain knowledge that the British officer will never salute without headdress, leaving the poor alien underling with a sense of confusion and hurt and the opinion that British officers deserve their reputation as arrogant w*nkers? b. Crisply return the salute - contenting Johnny foreigner no end but leaving you with a deep nagging feeling of guilt and self loathing deep in the pit of your stomach and a hope that no one's taking photos? or c. Pretend to start to salute but turn the movement into a brush of the hair as you turn away, pretend not to have noticed the little fellow and then slink away to have a word with yourself before spending the rest of the op/ex with your beret permanently on?
