Complaint about Service and Staff Behaviour

I'm writing to express my disappointment with the service at your restaurant. While the waitress who served us was excellent, the chef- Cash, was sarcastic and unprofessional when we raised concerns about our food not being properly cooked. He appeared disrespectful and was overheard by other customers, creating an uncomfortable atmosphere.I appreciate the efforts of Yolandi, who apologized and re-ensured our bill was adjusted accordingly. I'd like to commend the waitress and Yolandi for their professionalism.However, I'm concerned about Cash's behavior, which seemed bullying and unacceptable in a customer-facing environment. Worse was celebrating my daughters birthday.
