It’s not rude at all!

It’s best if you stack similar plates together and put the silverware on top or leave it separately. Its also hekpful to have any leftover food on the top plate rather than smushed in the middle. If all the dishes are different shapes, biggest on the bottom like a pyramid.

At the restaurant I worked, we had a bun for compost, trash, and recycle. So it could be helpful to keep trash out of the food scraps still on the plates. Please don’t leave trash in the cups, because we have to fish it out. Water is heavy and we can’t just throw out all the ice with the straw wrappers and the wrappers can’t go down the sink.
