We are having a backyard/barn wedding at the end of the summer. It will be catered by a restaurant but just to the point that they will set up a buffet, and we will be renting our own tables/chairs/china etc. I am having some difficulty figuring out the logistics surrounding clearing the tables after dinner. Do we just have everyone scrape their plate off and place them in a bin? That doesn't seem too classy to me. Any suggestions?
