A man angry over an expired coupon tossed a large cup of hot coffee into the face of a Dunkin' Donuts employee.
According to Philadelphia Police, the man frequents the store at North Broad Street and Wyoming Avenue in the Logan section of the city.
Earlier this week the man, who employees know as "Will" walked into the store and ordered a coffee. He tried using an expired coupon to pay for the coffee but wasn’t allowed to since the coupon expired, according to investigators.

After paying for the cup of coffee, "Will" got into a verbal argument with the woman behind the counter, investigators said.
During the argument, “Will” began to leave the store but as he walked towards the door he turned back around and thrusted his cup of hot liquid into the worker’s face.
The woman was treated at an area hospital for coffee burns and some problems with her eyes that persisted days later.
The entire incident was captured on surveillance video.
Police hope that someone knows who “Will” is and that they will alert detectives.
