wrong burger

went to buy a double boerie at Claremont main road, went back after I saw I was given the single boerie. Did not complain at all and asked for another chips for the inconvenience. The ladies started telling me that they could not do that and this is after I did not receive an apology for the inconvenience. Lady gave me the chips but with a stinking attitude. Not impressed at all and they burst out laughing as I was walking out.
