I think you will find it depends on what airport and airline you fly from/with.
As for security i think you will find 99% of Security officers are sick and tired of taking such items of people because of all the grief and abuse they get off pasengers and staff.They are only following the orders of the DFT and the Airlines.
Maybe one day the the Security staff alot of people slag off on pprune might save a few hundred lives including yours by doing a job you think is a waste of time.
