Removal from Google maps/reviews

I am from central Missouri, and have a question pertaining to an AMP in Columbia. That technically would fall on the east side board but it is dead, this board has much more activity so hoping to get some responses. Could be considered a general question but it happened with AMP in Columbia, Oasis. I was traveling out west for a month and decided to see if there were any new Google reviews before coming back. She does legit, but it is well known that she goes beyond that if she likes you. Some recent Google reviews alluded to that. I was surprised when she did not show up when I googled her, then even more surprised when I saw that she is not shown on Google maps- every business around her shows. When I got back in town I stopped to see her a couple times but she was busy both times. Any ideas why she is not on Google maps or search? She is on Mapquest and Apple maps. I would guess she asked to be removed due to reviews, but I thought a business could not remove themselves from Google? Just curious, any thoughts are appreciated.

People who have a business can have a google my business account.
They can update it, delete it etc at anytime

So that would remove any results from a google search - location, hours, reviews, etc?

it certainly makes things more difficult
