The table was furnished perfectly and then the servant would wait just outside of sight until the master had finished eating .The servant would not dare touch the table until the master was finished .Now if the master were done eating, he would rise from the table wipe his fingers, his mouth and clean his beard and would wad up the napkin and toss it on the plate. The servant would then know to clean the table for in those days the wadded up napkin mean't I'm done but if the master got up from the table and folded his napkin and laid it beside his plate the servant would not dare touch the napkin because the folded napkin meant I'm coming back.
