When he realized the phone was missing, the man returned to the restaurant, believing that employees had taken the device. The man went back to the drive-thru and "tapped on the window with a gun, demanding his phone," Phoenix police spokesman Sgt. Steve Martos told the Arizona Republic.
After leaving without the phone, the likely-impaired man crashed his car into a tree and took shelter at his apartment in a nearby complex.
No one could communicate with the man after he entered the apartment and it is believed that he was sleeping.
The standoff ended shortly at about 8:15 a.m. after the man woke up and surrendered to police. He was arrested on suspicion of aggravated assault.
Workers found the missing phone near the drive-thru.
