LOL!
My mum was a senior nurse in the Belgian military in the late 60s / early 70s and was stationed at the military hospital in Oostende. There was a naval rating who used to be a regular visitor to sickbay with a bad cough - and who would then be sent on leave along with meds until he got better. However, the frequency of his visits began to ring a few alarm bells, so the Colonel in charge did a bit of digging. Turned out that every time this chap visited sickbay was when his ship was about to deploy. So a plan was hatched.
The next time the chap turned up with sickbay with a cough, they made a big deal of it, sent him for a chest x-ray and stuff, and decided to keep him under observation for a few days. Plus he was administered large doses of various linctuses at set times throughout the day by my mum.
A few days later, Colonel Doctor turns up to check on the chap and asks him whether he was still coughing.
"I don't dare," was the answer.
P.S. You can guess what was in those linctuses of course
