Candy bar at reception/making a sign

So, I’m thinking a head for my wedding. I want a candy bar. I was thinking about writing a sweet little sign that says something like,

“Please be mindful of others while making your candy bag...”

Is that rude, prudish or anything? I’m going to have enough candy but I just want to make sure EVERYONE will be able to have one lol. Also, I’m a little OCD and I hate a mess (I know, who thing to have when it comes to a mess), but I also want to come up with something that basically says, “don’t make a damn mess and if you do...clean the shit up.”

LMAO.

OPINIONS PLEASE AND THANK YOU!
