"Tipping Point": Argument over tip at Chicago car wash led customer to kill, authorities say

(CBS/WBBM) CHICAGO - Knowing how much to tip is never easy, but it should never come to this.

Prosecutors in Chicago say a customer at a car wash shot and killed an employee, after the employee accused the customer of being a lousy tipper, in a dispute that apparently had a history, according to CBS station WBBM.

Marcus Gordon was denied bond Sunday after prosecutors outlined how he allegedly murdered Cesar Rosales, 43, after an argument at a car wash on Aug. 6 of last year, the station reported.

Gordon, 40, took his black 2002 Toyota Camry to be washed around 5 p.m. but got in a fight with staff after they refused to dry his car because he had a reputation for not tipping, Assistant Cook County State's Attorney Morgan Creppel said at the Sunday hearing.

Gordon left the car wash, but he returned 30 minutes later and shot Rosales in the chest, Creppel said. Rosales died that day at Stroger Hospital.

Before he died, he "stumbled into the store and made a dying declaration that the guy they had fought with earlier came back for him, came back to kill him," Creppel said, according to WBBM.

Gordon was identified by several witnesses and was eventually arrested Friday morning, according to a police report.

He has several prior felony convictions, records show.
