Some will always need care

A mentally disturbed (ill? diminished? challenged?) man is a regular at my coffee shop. He used to be casually, but nicely dressed, and someone in a newish model car dropped him off or picked him up. Now he sits outside and smokes and coughs. He used to sit inside and cough, and I think there were so many complaints to management (particularly around the free sample table) that they finally told him he'd need to use the outside tables.
