Investigators with the Lacey Police Department said a man walked into the restaurant and ordered a cup of coffee, but was upset over the 97-cent price.
After he received his coffee, the man poured it into his to-go mug and then demanded a refill from the manager.
Investigators said the manager asked the man to leave after he got verbally abusive about the price of the coffee.
The man then got upset and threw the cup of hot coffee into the manager’s face and fled.
Police said the manager had burns on her neck. KIRO reported that the manager was being treated for third-degree burns.
The man is being sought for simple assault, according to Lacey Police.
