A friend of mine told me a funny story about doing this. They had new neigbors that started stopping in each day - just in time for dinner so, my friends invited them stay for dinner to be polite . After this went on for several weeks and the people never extended a invite to return the favor, my friends started feeling a bit put-out.
My friends came up with a plan: So after dinner while they were still visiting with these neighbors - my friends wife set the plates down on the floor - for their dogs to lick clean and then she put them straight into the cabinet.
When the neighbors questioned her, she said "oh the dogs do such a great job and it saves me the work !" lol Needless to say the neighbors stopped showing up for dinner and if invited to stay - they would say "Thanks but, we have to get going" LOL
