I have dealt with this myself before and sadly I think many haunt owners have as well... here is the thing that is funny. People sit on this forums and bash each other, talk a good game, but if you see them face to face they have nothing to say they are nice as a peach. Here is another one... people behind your back will try to steal your radio promotions, your sponsors, your employees, steal your signs, trash your haunt to their customers, on facebook, in interviews on their website... blah, blah but when they see you face to face they claim they do none of that and want to be your friend during Transworld or something.
I've said for years some people are cowards, they are two faced they say one thing to you to your face and another behind your back.
This is just a reality... survival instincts kick in and people do what they think they need to do to grab your limelight.
Here is what I've learned ... Just ignore it. Do what you think is right do what you think is best for you, your business, your staff and ignore the rest. All you can ever do is what is right and in the end the people who focus their time on you will fail. Keep your eye on the ball and you will always come out on top!
