Spur unprofessional service, (not because the beer is cold and so cheap)

I visited Buffalo Ridge Spur, not impressed. The waitress argued wether I placed an order or not, in front of the manager. I had three beers while waiting, and after I finished the last beer, noticed there was no food coming my way. Got up and paid for what I owed. I promise I was not sticking around because the beer was cheap and cold. R100 for three beers and no food no service? Need I say any more? Not asked if I am ready to order, once. Seeing that the waitress claimed that I did not order. Should you like to confirm, I picked up the card from the condiments and asked for the special, you can see that on your CCTV. As I said, I do not appreciate being questioned by the person at fault, and that in front of the manager? Who does not step up and put the person in place, for her unprofessional conduct.
