The problem is not security staff doing their job its the total lack of common sense. You say you are slf so am pretty sure you don't have to deal with this
day in day out.
Can't take brie through but cheddar is ok, managed to convince them to let me keep the munster as it was not quite as soft as the brie.
Not allowed a bottle of water, but ok to buy a few liters of flammable liquid once through security.
Had a salad once to eat on the flight, was confiscated as could not verify the dressing totaled less than 100ml.
Have had a metal fork removed from my bag due to the security risk. On the plane have metal forks and knives, a couple of crow bars and also my right hand connected to a 275 tonne metal tube with 100,000+ liters of fuel in it.
Had a meatball sandwich from subway confiscated, although they agreed the sauce totaled less than 100ml you could in fact mash the meatballs into the sauce to create a paste of more than 100ml.
In some countries/airports it is totally out of control.
