JUNCTION CITY, Kan. (KSNT) – A Junction City McDonald’s told KSNT News they are investigating after a police officer said his coffee had the words ‘f***ing pig’ written on it.

Herington Police Chief Brian Hornaday said on Saturday that a Herington Police officer went to the McDonald’s at 1127 South Washington Street on his way to work. He ordered a coffee and discovered that someone had written ‘f***ing pig’ on the side of it.

Hornaday said when the writing was brought to the attention of management at the McDonald’s, they offered the officer a free lunch.

In a statement, Chief Hornaday said the officer has worked in law enforcement for five years serving as a Military Police Officer in the United States Army. He’s worked at the Herington Police Department for only two months.

A general manager at this McDonald’s told KSNT News, “We take this matter very seriously and are investigating it right now.”

Hornaday said they will not be releasing the name of the officer who received the coffee cup.
