Slow service and non allocation of points

I recently went to Spur at the Fig Tree in Port Elizabeth. The service was a bit slow, but understandably it was getting busy, but to ask three different waitresses for extra napkins was quite odd. I gave my Spur family card when I paid, but when I checked my balance, nothing was added. I found this incredibly frustrating, because even though I did not spend hundreds of thousands of rands, hard earned money was still spent and no reward for it.
