I know pictures don't do it justice, but as a concrete guy, I don't think it looks that terrible. You're always going to see "swirl marks" from finish machines when it's green. There are a few areas that appear to be a bit rough against the wall, and it looks burnished on some of the overlaps, but most slabs that are taken to that level are.
What is/was the final plan for the floor? From what I can tell, every Menards floor is slightly ground, and definately treated as well.........
