When my kids were in early elementary school we had a "manners supper" We made a huge game out of it - the supper was to be held on a specific night and they kids had to earn so many points to attend. Each night at supper they could earn X number of points by putting their napkin in their lap, keeping elbows off the table, etc. They could have points deducted for each infraction. They ended up all 3 being able to attend the special "supper" (we had their favorite foods/desserts). After that time, we haven't had any problem with manners, but it wouldn't be too hard to repeat if needed.
