Dissatisfied customer

It's is currently 9 o'clock,my fiancé and I came to McDonald's for our usual breakfast order,we were served well by Thabile at the counter that we paid for our meals however the ladies at the Mcafe station were rather rude. We stood there asking if the stuff at the bakery was fresh,the laughed at us,as per her colleagues her name is Sne,my fiancé continued to ask them if we are invisible because they kept ignoring us and walking up and down,and the lady said yes we are invisible... I am very unhappy with the service we received from this lady... Please teach the staff proper customer service
