Bad manager at Wimpy Zeerust Thabiso

I have always enjoyed my breakfast at wimpy all over south africa.over the past weekend I was travelling to Botswana and decided to get breakfast at wimpy zeerust (north west)on my way there ,was bragging to my friends about the fully loaded dagwood .as we sitting waiting for our meal a guy came in a black shirt told us we were making noise .he was arrogant and rude .when I went to speak to him he was very dismissive and disrespectful .the were other people in restaurant obviously of a different race laughing loudly and he did not even tell them to tone it down .What happened to treating customers fairly regardless of gender or race????I was very disappointed to hear that he is the manager on duty ,I wonder if they make their budget as am certain I wont be going to Wimpy.will have to look for another place to eat my breakfast as I don't think Thabiso values the money I spend at wimpy .He refused to give me his staff code or area manager contacts .he gave me customer care line as he knows I wont get help there???how do you give someone like him superior tittle I dont know as I think he needs to go back to customer service training and learn consumer law .
