A customer angry about his order at the McDonaldâs on Branch Avenue Thursday night went inside looking for a fight with the cook. The police said the cook agreed to fight the customer and others in the parking lot, until he heard one of the assailants yell, âGo get my gun!â The cook, Shaheed Miller, 27, told police he pulled out a pocketknife and started âslashing wildlyâ at the assailants, so he could get to safety inside McDonaldâs, according to a police report. Miller cut the unhappy customer, 25-year-old Jacob Velazquez, in the face, arm, and back, according to detectives.
