Uh, there's a window well...

So the tree guy I had called to come trim our shrubbery was hard at work.
The saw was buzzing and the branches were flying.
It was already looking better outside my office window.
The bushes had been growing out of control since their haircut from a couple of years earlier.
The interior ones had shot up and the whole area was pretty wild looking.
I had called the trimmers back.
"Just do what you did the last time and make it all look better," I suggested before I retreated indoors.
"Watch out for quail nests, though."
They were busy for a while.
I heard a couple of shouts when they surprised some wasps in a nest deep inside and noticed the one guy standing deep inside the greenery. But I didn't think a lot about it.
When I came out with my checkbook to survey the results, he started explaining why he was in the middle of the bushes.
"I wanted to try and lift the branches so they would fill in the hole there," he said, pointing to where he'd been.
"There's one over there too," he said, gesturing to the other side.
I looked at where he was looking.
Yes, there is kind of a hole in the center on both sides, right where the window wells are.
"Uh, there are window wells there," I said. "Maybe I should have mentioned that."
The guy looked at me.
"Really? That would have been a surprise," he said somewhat dourly. "That would explain a lot."
I wonder if you can be sued for damage to a hedge-trimmer who isn't informed about a window well?
