Just happened two weeks ago.....so....
In a dead-serious tone of voice, I tell them that we reserve the option to jack up one side of the the floor (or ground) to make it look more level. Then I proceed with some nonsensical method of shenanigans.
They always get that "Edith Bunker" look on their face trying to imagine how that works.
It's almost as fun as screwing around with telemarketers....
But all silliness aside...there is such a thing as "level" and "optically level"....much like "centered" and "optically centered". Optical illusions can be a real pain in the arse if you're not careful. Uneven ground, weird signboard shapes, and certain typefaces really can make things challenging sometimes.

We got.contractdd to produce and put up 40 window films at 20 different locations as part of our hospitals advertisement. They were kind of like a cling.. But not a cling. I opted to do most of them overnight so I didn't have to put them on opening doors with hundreds of customers coming through.
There was one place, a bank who wanted us to do it in the daytime... Most banks don't like people working on their windows at night. Anyways...
Went in, introduced myself to the manager...he showed me which window, and I put it up. As I was packing the truck up.... He comes out with a weird look on his face and says it's crooked. I assure him it's not... Go back to the truck to get a tape measure and show him... But it still "looked" crooked to him. It was his building.. So I took it off... Asked him where he though it was level... Once he was happy I put it up, and he said it was perfect now. It was a good half inch off, and I could easily see that... I think he was standing on the wheelchair ramp and looking at it that way. Showed him it was half an inch off... But he said it was perfect, so I left it.
Sure enough when I send all the photos to the owner of the company, and to the hospital.... They both easily notice the one is crooked and want me to go back to fix it. I told them to speak to the manager whos decision it was on where it goes.
I got the nickname "Mr crooked" by the other installers for about a month because of it. It was so bad, but sometimes you cant argue with stupidity.
So id say there is level.. Optically level..and stupidly level.
