The notice on entry to the security zone says something on the lines that security staff have the right to work without being verbally or physically abused
Remarkable how this notice is only displayed by railway and airport companies who realise that their appalling treatment of customers and rotten service standards, together with their employees' attitudes and behaviour, are likely to provoke uncontained, murderous rage in a nun, let alone in the average person.
The notice really means:
Having paid an exhorbitant sum for the service you expect from us, you are now going to be delayed, harassed and shoved around by a bunch of cretins obeying our incompetent and invisible management's directives to the letter, which have been read very slowly to them because they have between them the IQ of a bar of soap.
If you react in any way other than subservient acquiescence to this appalling treatment, the cretins have been told to accuse you of being disruptive and summon the police to arrest you. DO NOT ARGUE OR RESIST.
