Unfair treatment to clients and poor service

I went to chicken Licken mamelodi crossing on the 24/02/2018,19:40 order numbers 20524 craving for hot wings,when I got there I was told by Ellen they have ran out of stock for the night which I understood because it was late and was almost knock off time,then I decided to buy "just 4". As I was waiting for my order to be served,a male client walks in and asking for wings too and was told they only have 4 big wings waiting just for him...I was so shocked after I was told they didn't have any wings left...where is the integrity in all This,why didn't she offer me too the wings that were still there so I can make my choice of buying them or getting something else,I am so disappointed with our sister who still treat us like nothing compared to man..
