Found the following article online, use it to answer the question: What was the name of the restaurant manager who was rude to Madea?  Shirley, goes to visit Dr. Evans with family friend, Aunt Bam about her cancer and finds out that it has gotten worse, and that she may only have a few weeks to live. She asks Aunt Bam to call her children so she can invite them to dinner to tell them all at the same time. Cora and Mr. Brown (David and Tamela Mann) are also at the hospital, to get Mr. Brown a check-up. Dr. Evans tells them he has to do a colonoscopy on Mr. Brown, and they find a growth that needs to be removed surgically. Meanwhile, Madea furiously and violently drives her car through a restaurant named 'Smax', because they stopped serving breakfast for the day, and because the manager had been very rude to her. Shirley's children Byron (Shad "Bow Wow" Moss), Tammy, and Kimberly arrive at Shirley's house later that day for a dinner Shirley has planned for them in order to tell them the sad news about her recent prognosis. Byron arrives with his girlfriend Renee and his baby Byron Jr. Tammy arrives with her husband Harold and their two kids, with the former two subsequently carrying their argument over directions to the house with them. Kimberly arrives with her husband Calvin. Tammy and Kimberly then start to argue when Byron's ex-girlfriend Sabrina and "baby mama" (Byron Jr.'s biological mother) arrives. Sabrina quickly gets on Byron's nerves by addressing him as a "drug dealer" (since he was one when he was young and got arrested for it). She also lies excessively, uses her son's child support money and supplies for herself, and also tries to goad Byron back into selling drugs, so she can get more money for herself in the process. Moreover, she also turns out to be the manager of 'Smax', the restaurant that Madea crashed her car into earlier that day.
Answer:
Sabrina
