The lady said that she's headed for her volunteer job at a homeless walk-in shelter.
“What do you do there?”
“Serve meals, play cards, and whatever's needed.”
“Must be nice to do something good?”
A homeless man interrupts the women. "Excuse me, ma'am, can you spare a cup of coffee?"
The barista told the man that she couldn't give out free drinks; it's against company policy.
The volunteer smiled. "It's your lucky day, sir. I know where you can get coffee and a donut."
