Police said the man allegedly showed the staff he was carrying knives and demanded the food be prepared for him.
“Fearing for their safety, the staff commenced cooking his order and notified police,” WA Police said in a statement.
“Perth police attended the scene under emergency conditions and arrived a few minutes later while the man was waiting for his order.
“He was arrested without incident.”
The 24-year-old man from Parmelia was refused bail and faced Perth Magistrates Court today on several charges.
They include threatening to kill, being armed in a way that may cause fear, and failing to comply with a request to give police personal details.
However, he is not accused of armed robbery because he paid for the chips.
