Concrete Substrate Out Of Tolerance


I am laying tile in the mens and women's restrooms at a bar. The concrete is badly out of tolerance. It has multiple "peaks" about 3 1/3 to 4 feet apart with up to 1/4 drop at it's lowest point in betweens peaks, basically a wavy floor. My issue is that the bar owner doesn't want me to grind at all. I'm thinking I need to float between the peaks with some kind of patching compound to achieve tolerance. Recommendations? Suggestions?
Fyi: I will be tiling with 8"x40" wood look LFT.

Heavy D. The floor in both bathrooms are out of level leaning towards floor drain so I scratched that idea. I also can't raise the floor because owner wants to eventually transition same tile into main bar area, therefore I can't raise floor by too much.

I am not sure what the issue it. Grind it and make it right. If the owner has an issue with that tell him to start serving alcohol without anything to pour it in. When he says he can't do his job like that you say exactly. I don't let customers dictate how I do my job. If they do, then I ask them were they send my W2 next year.
