Suspected of Performing Personal Training Duties

Today i was accused of performing personal training duties by the Club Manager of Virgin Active Randburg Malibongwe. He came to me when i was waiting for my friend on the tredmill and he asked if the person i was training stomach exercise with, what relationship we have? I told him, she is my friend. He told me that i should stop performing personal training deities because that is not allowed. I said to him, if someone i train with is doing the wrong exercise must i continue to watch her doing the wrong thing and his answer was it is the duty of the personal trainer to do so. Firstly, personal trainers at Randburg are not friendly like other personal trainers at other gyms e. g Bryan Park, i went there and they made me feel welcomed even though i was not their clients. They know business very well and how to approach customers. The Branch Manager told me not to train with my friend and refer her to personal trainers. Gm is the place to have fun and to distress not to be controlled. i read the policy and what i did is not what is written in the policy. I am paying customer and i am not training for free. I cannot be told that if i continue, i will get a warning. I am so upset.
