Adolf Anderssen's Queen odds

Alright, this one bugged me a little since I read it in my childhood times... I will try a roughly translation
here so sorry for my crummy English. It's about a anecdote of Adolf Anderssen, but I want to know if this "anecdote"
has some truth in it. I did the usual before posting this(Wikipedia, Google Search without success). The main reason I
post this is because the book in question where I taken this story is notorious to twist some facts by its author. So if anyone has a good
 background of chess history could indeed be really helpful.

Alright here it is (I took the leisure to embellish some part here since the original text was a bit painful to read-:)):

---------------------------------------------------------------------------

In Austria, almost at midnight, see our "hero" Anderssen trying to search a place to call it a night. Arrived at such
a establishement, one could remark the innkeeper seriously absorbed about a certain position on the chessboard. After supper,
Anderssen tried a approach to play some casual games with him. The inkeeper, not knowing about Anderssen and thinking facing some random beginner, scornfully responds:

- Very well. But we do it at my own terms; I play with handicap, meaning I give you the material advantage of a whole Queen.

A couple of games has been played where Anderssen loses(!?) both of them. A bit perplexed , he admitted:

- It's really curious. Being up a Queen seems to have a negative effect on me. With such a powerful piece at my disposal,
i'm very afraid to lose it thus damaging my whole playing abilities. I therefore propose we doing the opposite; that's I give you
the avantage of a whole Queen!

The innkeeper was about to refuse at first after hearing such insolence especially after the trashing he has done do his victim, but then finally
accepts thinking it will be a simple formality. But then it happened. Like magic Anderssen makes his minor pieces rampaging the whole chessboard,
scoring victories after victories. Finally after a dozen games, the hapeless victim stop the massacre and with dismay declared:

-Never shalt I understand this accursed game! as his guest retired to hit the sack...

--------------------------------------------------------------------------

So that's it. Even though I mentionned it at the beginning as this being a anectode, was this Anderssen's feat did really happened or
was his "groupies" entirely made this up to make their man even more "immortal" that he already is?

Thanks

So no one know?

It's not that I care too much about it, but just wanted to know if the source I took this was reliable at all.
