Superspar not super

Today I purchased honey and oats bread at Kraaifontein Superspar. On my return to work the chef noticed a tear in the bag. My question is: this is a Superspar. Should the consumer have to check all purchases, or is Spar saying they do not have to do it, as it is unlikely to be returned? Also, at the speed checkout 5 ladies were looking at me, but only 1 was assisting clients. Is this acceptable to Spar???
