[WH40K] On Blessed Holy Terra, a meeting of certain and exclusive dignitaries including an admiral or two will attend private dinner. The guest hotel where I work has been given the responsibility for hosting the event and planning the dinner menu. What do I need to know for success?

You won't have to worry about food as long as it is plentiful and varied, and you won't have to worry about decor as long as it is tasteful.

What you need to worry about is security. Any meeting between dignitaries will be a prime candidate for ambush, heresy, or spying. Expect there to be a LOT of muscle. Arbites will be on constant patrol, and probably stopping to question anybody that comes within a mile radius of the structure. You will probably see military personnel, and it is best not to interact with them. If you are really lucky, there may even be some Space Marines present. You will not want to even look at these guys. Catch a glimpse when you can, but don't you dare stare. If you make it look like you're sizing them up, they will cut you down to size. These guys are not going to take any chances. There will be no warnings, no slaps on the wrist, and no mercy. If you are caught doing something you aren't supposed to be doing, you'll be lucky to simply be thrown in a penal legion. 

You will be expected to forget anything that you hear. You shouldn't be listening if you enter the room where these dignitaries are talking, anyways, but if you do happen to hear something you will cleanse it from your mind, or it will be done for you by force. 

There is a non-insignificant chance that, despite all of these precautions, something will happen. Maybe a spy will be caught recording, or maybe an assassination attempt will be thwarted, or maybe heretics will try to summon a demon. Regardless of what happens, you will step aside and simply pray that nothing happens to you. If it is spy activity, you will probably be questioned even if you were in a completely different part of the structure. If it was an assassination attempt, you will be questioned to make sure you aren't an accomplice. If it is heresy, you will probably be killed outright because they don't take any chances with that shit. 

All you should know is that this is an incredible opportunity for you and your business. Do everything right and you could see more of that kind of business coming in, which will make your life better in general. If you mess even one thing up, though, chances are that you will never again have such an opportunity.
