Not about the sale

I recently went to Game Kolonnade Montana, Pretoria. At the till point as the cashier was ringing up the goods, she saw that I had taken a certain brand of apricot jam. She then asked me if I knew there’s another one on special for R13.95 (900g). I said no. Then the supervisor went to see if there were any left and she came with one. Now that is 5 star service to me. They do care about their customers and it’s not about “the sale”.
