candy buffet

is there any type of poems for the candy table? would it be rude to put a sign in a frame that says one bag per guest please? just wondering. i finally decided to do the buffet and i am excited about it.

you can probably make a cute little poem and in the poem have a line about one bag per guest, just off the top of my head you can put something like this at the end

so there is enough candy for the rest,
we kindly ask one bag per guest
