Iowa City Police were called to Gateway Plaza just before 8pm after a caller reported being assaulted by the manager. Police say the caller, identified as 35-year-old Arby's employee Gabriel Keith Usher of Ridgeway Drive, had been fighting with his manager, 24-year-old Matthew James Dugger of the Western Hills Estates manufactured housing community in Coralville. Usher had taken issue with Dugger's status and work ethic at the restaurant. Dugger told investigators that he ordered Usher to "stop with the attitude", and Usher responded by "getting into" Dugger's face.KCJJ reports that the men quickly began brawling in the restaurant and making a general mess of the place. Both men face up to 30 days in jail if convicted of these charges.
