Rude staff members

I have been a member at Virgin active for more than ten years and today I was so shocked and disappointed. I work in Midrand and get home around 7 o clock. This is when I am able to go to the gym. After my workout I like to use the sauna for a few minutes (this is one of the main reasons why I have chosen Virgin active as no other gym offer the sauna option). Tonight at 08h30 I was chased away by one of the staff members, and when I asked about why she said. She wants to go home. This to me was extremely rude and humiliating in some way. Nowhere does it say that the sauna shuts off at this time. Please let me know if this is the case. After tonight I am considering another gym. I don't even want to go back as I have mentioned I feel humiliated. This was Virgin active Vanderbijlpark branch.
