Has anyone ever gotten information from Spitzer?

Devon says to ask Spitzer for information about mercenaries in the area.

He never says anything.

Doesn't that suggest he has something to say? He says nothing.

My interpretation is that he knows nothing about the Quegian mercenaries, and is only interested in playing dice.
He is "happy to talk to you" in the sense that he is willing to sit down with you and play, but he does not actually want to talk to you.

From the "BAK Help web" (to be found at "dimwood.net):

Tom's Tavern in Tanneurs is important to a complicated Quest. If you have talked to Devon in Eggley, he will have told you about the Collector. If you have also talked to the Priestess of the Temple of Silban, you will have accepted the Quest - to find the Collector, so he can be punished. If you now talk to Spitzer at the inn, he will indicate that the Collector is in a back room of the inn. You will have to spend the night here, if you want to meet him. Later you can pick up you reward from the Priestess of Silban.
After the Collector has left, Spitzer will want to gamble with you. But remember to Bard first. Now gamble with Spitzer, until you lose. Surprisingly, you can now Bard again, receiving the highest fee. If you repeat this often enough, you can get filthy rich! (This is a bug in the game. A more detailed description may be found in the Chapter 1 Walkthrough.
