Heathrow a rubbish security and poor staff attitude are well known and almost parametric to the airport experience fir many years now. Ditto for JFK CDG FRA and many others.. but no one does anything about it. I suspect they cannot ... Smart people don't join the security business as a rule, and plenty of dodgy people who enjoy low status power do ( this assertion has some cross country research backing it) hence not much you can do with the raw material.... Those who can motivate this lot of losers (HKG, ) deserve a medal!
