Germiston shell garage manager RUDE

I had a manager (from Germiston shell opposite caltex) that poured out my bottle of water this morning and he instructed me NOT fill my bottle with water and I should pour water from my house because he pays a bill of R27 000 and I should never pour water from that garage.

I always pour my petrol from this particular petrol station. I also recall him filling water without a problem bur to date on the 3rd of December he was so RUDE and I did not even reply as I am not feeling well. I just wanted water nothing else.
