Is vinegar a privilege at KFC?

I would like to find out if getting vinegar with your order from KFC outlets is a privilege or not. In so many instances one has to fight for vinegar. Yesterday, I even requested the manager on duty at KFC Rynfield by the name of Nikiwe Sibiya. She just told me that it is finished. No apology offered. I think this is really a bad service as some of us would like to have our meals with vinegar
