Swiss International Airlines - Virgin Atlantic JNB lounge for LX passengers

I am sitting in the VS lounge in JNB where I just found out LX uses for its first class passengers.. What a great lounge.. Food includes ginger and beef dim sum, incredible burgers, and a wonderful bar selection including an odd but wonderful champagne.. Joseph Perrier.. BUT they are very strict in their admitting policy.. They would not allow Swiss business class passengers Lufthansa first class passengers in.... Great experience...
