Alot of posters here have quoted "The rules are the rules" etc. etc. I think you are missing the point.
I for one also wonder what happened to common sense where the crew were concerned? It appears that in this case security dont have a problem with the carriage of a diabetics syringe/Novapen/insulin or whatever. All I can see is that Big Airlines has dropped the ball with their customer relations and gotten itself some bad
PR - Again!!
Someone made the point that the passenger involved may have lived with carrying around a Mars Bar and his insulin pen/syringe all his life so didnt think it worthy of comment as it was his normal life. My late mother was a diabetic and I can only endorse this view from experience. If you dont think you are different or have any special needs, you dont search a website to find out these rules do you?
