Bad service

I went with my family to Spur Sunninghill it was my son bday so I knew that at Spur they will sing for him tjo to my surprise we got there and the waiter first of all was a trainee he didn't know what was on the menu or what he was allowed to do and not to do I called him to ask if they would sing and he advised that his manager said he would have asked us if we celebrating a bday or not cause we already ate and they cannot do that now the manager ne is Lenny .The manager came and tried and explained but was very arrogant and I actually told her it's fine qe ready to leave we don't need them to sing anymore after all that drama .the moral of the story here is don't treat people different because of color the reason why I am saying that is because a few tables away they just sang for an elderly guy and refuse to sing for an 11year of boy
