For whom? Aldi who is highlighted? Google who is paid? Or the poor suckers trying to find something?
A subtle dark pattern that Google uses is that they have roughly one size of POI, so there isn't enough space to show everything, or most things, it has to pick and choose. That artificial scarcity is tied to the profit motive (pay for prominence) and is user hostile.
Sure, grocery stores are most common, but often you're looking for something else. Using small icons, smaller text, or some other UI affordance to facilitate finding what you need nearby, quickly and without text searching, would be great, but isn't in Google's interest.
