Split a molten cake?

I think this is one of the first times I have encountered a guest requesting us to split a molten cake onto two different plates. Their server--a newer one here--rang in the modifier. When I confronted him, he said he knew I wouldn't/couldn't do it. I laughed at him and said, "Why did you make me tell you 'no'?" Then I get all this info regarding the guest that doesn't change my mind in the least. A molten cake split in half would look horrific. Murder on a plate.

It went out as God, er, I intended. And they made the server split it right there at the table in front of them.

Sheesh. People.
