So, for our wedding, our venue is in the second floor in an old victorian building. It doesn't have a place to wash dishes and we have to get everything out that night. We are going to use fancy plastic plates, etc, so they can get thrown away in the end. We'd like to put up small signs on the hors d'ourve tables, dessert bar, and even the buffet, to ask our guests to reuse/recycle their plates and cups, so guests aren't just taking one, putting 1 thing on it and then tossing it and getting a new one. Yes, this is to conserve waste and also to save our money so we don't have to buy a million plates just for all of them to get wasted. My question for all of you is, what's a nice way to say hey, "save your plate"? The only thing I've thought of is "to conserve waste, please save your plate". Any other ideas are welcome, and saying about cups for the bar would be helpful too!
