Bad attitude/not helpful

Went to Spur on Sunday 10 May for Mothersday breakfast and although it was extremely busy and the service a bit slow we understood this and did not make anything of it. When I went to pay however the cashiers attitude was not what I was expecting. Firstly when I gave her my debit card to swipe I gave my Spur Family card together as I have points on the card. She swiped my debit card and only when she gave me my receipt I saw that the points was not deducted. I immediately asked the Cashier and she said in a very harsh manner that she is not able to see who has got points and who not and there is nothing she can do regarding this now. I asked her why do you think I gave you the family card together with the debit card and she just said : for swiping it and started doing something else and talking to the waiter that was standing at the door. I waited for her to answer me but she just ignored me. Very rude and definitely not good customer service. Will definately think twice of standing in a ques outside, wait long for service/food AND to top it of get bad attitude from a cashier and then rather go somewhere else.
