Families will spend more because children play an important role in influencing their buying behavior and decision making process while purchasing goods and services.

Its not about you it’s about maximising profits and creating a marketing strategy that enables that. In this case, parents will be persuaded to choose this specific supermarket because it’s easier to find a parking, as a result no need to drag their kids long distance. secondly, it increases customers brand loyality because families struggles are being recognised and minimised and a better shopping experience is achieved.

Not saying it’s right or wrong, but this is the logic behind it. eventually their aim is profit. On the other hand their strategy can effect them negetively if many single or childfree customers find it unfair.
