What McDonalds did was to train the dining out public to bus thier own tables. When this first occured in the late 1960’s I used to leave my tray on the table for an employee to take it away .I don’t work for them nor draw a salary from them I used to say.Just Like a trained circus animal the public soon learned what is exspected of them to do.Not only do we have to bring the food to the tables ourselves but bus as well.
