A little bit of gratitude went a long way at a Fort Worth ice cream shop.
Sweet Sammies shop owner Kory Close says a man named Gary came in to buy water, but ended up paying for over one-thousand dollars worth of treats for customers in three hours.
Gary also tipped the staff 300-dollars.
Why? According to the Fort Worth Star-Telegram, it's all because he got a parking receipt validated there and just wanted to return the favor.
