Bad service

So I was shopping at pick n pay Benmore gardens round about 04:30 30 minutes till they close, most of the staff memebers are in a rush to go home understandable after a long day but I think in the eyes of the customers you still have to act right and professional which was not the case. So at this time they mostly mark down items and I've noticed in most cases the staff memebers hide the items marked down items for themselves I was asking a lady about hot food and honestly she couldnt be bothered she was husy with her mark down food as I was paying same lady was behind me with all the mark down items now of these items are staff perks/benefits why is it not done when all customers are gone? Then it wouldnt affect customer service I've noticed on other days but today was just to bad ended up not buying the hot food and settling to buy myself Nando' s where I got excellent service.
