Sometimes there are people think about unimaginable things that impossible to implement that's why they should do some realistic check before suggesting those things come up on their mind. Since there's nothing gonna happen with bad suggestion especially if the casino is on disadvantage side with it.
Also for sure casino won't implement anything that can kill their business.
But there are really good suggestion posted here and if casino owners could read this thread maybe they can implement some of those especially those real beneficial to their gamblers.
That applies to all the works, simply people do not know the work to which they approach the imaginative requests therefore well.
Just explain to them how it works and the reason why it cannot be done and everything settles in my opinion
This certainly helps people understand why their proposals or ideas are discarded.
I do so with my work.
