Courtesy Please

M.B. came home with a horrific tale from his subway ride home tonight. A man kept his bag on the seat during the crowded, rush-hour commute. No, that's not the worst offense. A lady boarded the train and asked the, dare I say, gentleman to remove his bag from the seat so that she may sit. He refused. Now this is clearly RUDE. From Mrs. Humphry's guide to riding the omnibus (applies towards all public transport)...

True courtesy, for instance, will prevent a man from infringing the rights of his neighbours on either side by occupying more than his own allotted space
