Poor Service

Was at McDonald's Waterfall Mall Rustenburg now at about 08:52 ...got a very long que, with only one cashier, when I asked her if she was the only cashier, she just said yes, "with an attitude". The lady before me order Big Mac meal and she was told that they had no fries?and it was my turn, I order a Breakfast wrap, AND THEY ALSO SAID, THEY DID HAVE THE BREAKFAST WRAP in the morning ?...there was no note whatsoever that at least infomed that long que of customers behind me that they don't have anything this morning ???
