Amazon is famous for their customer service - but one worker has well and truly raised the bar.
Delivery driver Stephanie Lontz has been hailed as a hero after defending a customer's daughter and her tiny dog from a rampaging pit bull.
Her brave deed was captured by a door cam in a dramatic video that has since gone viral.
Lontz was making holiday deliveries in suburban Las Vegas when the incident occurred. In the video - which shows a front porch and garden - 19-year-old Lauren Ray can be seen trying to calm down a pit bull.
Ray can be heard saying that the pit bull isn't her's but she plays with it for a few moments anyway.
But when Ray's own dog comes running out to say hello, things turn nasty. The pit bull becomes suddenly aggressive, barking and snapping at the little dog. Ray picks her pet up and tries to protect it - but the pit bull won't leave her alone.
The teenager screams for help, trying desperately to protect her little dog from the snarling pit bull. Just when it looks like she's in serious danger Amazon driver Lontz rushes to the rescue.
"Stop! Get back!" Lontz shouts at the dog, stamping her feet. She bravely puts herself between the pit bull and Ray, telling the girl to "get in the house!"
Only when Ray safely inside does Lontz walk away. "You're a bad dog!" she tells him before striding back to her vehicle.
The girl's father Michael Ray publically thanked the brave delivery driver in a post on Facebook, in which he also included the footage from his ring doorbell cam.
"She could have easily stayed back (she saw how aggressive the dog was) but came flying in to help without a thought of her own well-being," he wrote in praise.
"Plus her telling the dog he was a bad dog at the end of the video is classic!" he added, before letting people know that his daughter and her pet had a few scratches, but were otherwise okay.
In an interview with Fox5, Lontz humbly accepted his praise: "I'm just glad I was here to do it."
She also suggested that protecting customers was all in a day's work for an Amazon driver.
"Two days prior I had been bit by a dog, two days before that I had saved a baby that wasn't even two years old yet- locked in a house," she said.
