This is a great story about the kindness of strangers.

Christina Summitt is a cook and bartender at the Holiday Inn in Clinton whose Great Dane-Black Lab mix, Tucker, needed surgery because the dog had swallowed a tennis ball.

While tending bar, a man and woman saw the tattoo on her wrist of dog prints leading to a conversation about animals; and that’s when Summitt told him of her predicament.

Summitt mentioned that the ball was going to have to be removed and the surgery would cost $2,700 - or else the dog would die.

Besides her jobs - cook and bartender at the at the Holiday Inn - she also works a couple of days at a deli; and volunteers at a pit bull rescue shelter. Her husband works full-time and Summitt has three stepchildren. Suffice it to say, they have love in their hearts.

"The couple ordered drinks and dinner at the bar. When it was time to close out their $80 tab, the man filled out the receipt with a tip -- for $1,000. Summitt said she started shaking and crying. She showed the bill to her sister, who tends bar with her, to make sure she was seeing three zeros after the 1. . .

Hotel manager Michelle Satanik told CNN. . .  'Apparently this man does this quite frequently. Just a really nice guy and humanitarian,'"

Summitt says she's since gotten messages of support from all over the world.

"I would also love nothing more than to publicly thank this couple in front of the world. I've never seen a random act give so many people so much hope," she wrote.

Tucker is recovering at home.

Props to the stranger whose kindness helped save a dog’s life – and gave joy to a woman whose companion was saved.
