 * Have life like fantasic beasts in the pub using simple animatronics. For instance a phoenix in a cage behind the bar. Of course a niffler could guard the lost and found box.


 * There is technology where an ad appears in a bathroom mirror activated by a motion sensor. Use this to have a magic looking font appear telling the customer to wash their hands or compliment them on their appearance.
 * Likewise you could plant a little hidden speaker in the bathroom and have an annoying unseen poltergeist shouting abuse at people entering.


 * Use little helium filled balloons to imitate the dirigible plum plants from the Lovegood house where the fruit hangs upside down
