SPOOKY SAFETY - please don't forget the safety element of Hallowe'en this year - ensure any costumes are fire retardant (especially important for children) - if you aren't sure then spray the clothes with fire retardant spray which is easily available from various suppliers on the internet.
DIVERSITY DOOM - have you an updated diversity policy? Ghosts and zombies were people once and should be included. Or perhaps that is just witchful thinking?
GHOSTLY GRIEVANCES - never summon what you cannot banish - and if you get stuck then give HR Vision a call
Bats all for now, eat, drink and be scary!
