All these suggestions are awesome, some lovely person messaged me to add something I put on another thread
*** Zero tolerance on abusive behaviour, police will be called if necessary ***
I think anything that makes these cunts think twice has to be a positive thing.
I've seen similar notices out and about too and EG you are right, our industry does seem to attract more weirdos than others. The nature of what we do makes us vulnerable whether we like it or not, whatever precautions we take. Standing up for ourselves and making it clear that we don't take any shit might actually drum home the message that it won't be tolerated and no, cunt, you WON'T get away with it.
