Preface: For some reason I cannot see the image you attached. However, without seeing it, I know that you can exclude the "wavy glass thingy at the floor" from the lighting, so it does not create the reflections your boss does not like. It could be done a few ways. The first being to select the object, right click, and go to properties. In that menu there is an option to exclude from global illumination. This likely will still leave your relfections. You also could adjust the far attenuation of the pinlight light sources, so it stops light before it hits the glass thingy. Another way would be to select the material for the glass thingy in the materials editor and flag it as opaque.
Also, you could change the light source to "ambient only", however that will mean the light will not cast any of the shadows you're looking for. I would adjust the far attenuation of the lights until the reflections look like you want.
Good luck.
