Simone Myjel Carter, 26, was given credit for already serving 93 days in jail by San Diego Superior Court Judge Polly Shamoon, which includes good conduct credits.
No restitution was ordered for the Sept. 6 incident at the Pharaoh Hookah Lounge at 976 Garnet Ave. A 21-year-old employee was injured at 11:40 p.m. when he tried to eject Carter after he caused some problems in the lounge.
Carter pulled a knife and stabbed the employee twice. The worker was taken to a hospital but the injuries were not life threatening.
Shamoon denied probation and imposed four years in prison which Carter had agreed to accept when he pleaded guilty Sept. 20 to assault with a deadly weapon. The maximum sentence was eight years.
Other charges were dismissed including two assault counts of a woman and another man and vandalism. Carter has previously been convicted of robbery, records say.
