I can think of a few more controversial ‘tests’, the A&E consultant who requests 50mls ice cold water to ‘inject’ at high pressure into the ear. The ambulance tech that was suspended for checking blood sugar levels by inserting half a inch of needle between the finger and nail. Doormen who ‘Accidentally’ apply steal toe boots onto the casualties fingers when kneeling down. I like the brain fluid test.. hehe may have to try that one!
