Good Manners at the Table

I teach at a non-profit school for children with autism and other developmental disability.  My students are age range 16 - 22.  At this age, many of my students have taken an interest in dating.  However, I have realized their table manners need a little work in order for them to be successful with this natural part of being a teenager.  Telling my students "they'll get more dates" if they have good table manners is highly reinforcing for many.  It's also a fun and age appropriate way of teaching this lesson.
