Rural Carrier Tammra Billings was recently delivering mail on a snowy day in Whitewater, WI, when she spotted an older customer waiting to cross a road.
Billings and the customer exchanged smiles and waves, but as she prepared to pull away from a mailbox, she looked back and saw that the woman had fallen.
The Postal Service employee stopped to check on the customer and found her bleeding from a head injury.
Billings called for an ambulance and rendered first aid until emergency responders arrived.
She then departed to finish her route, leaving her coat with the woman to help her stay warm.
