[@Dark Cloud] I would think of it like this instead. 

Completely whip the encounter out of your mind right, instead the party arrived, the tavern was hosting a drinking contest, our group and your character joined in, we all got shit faced drunk (maybe there was a small bar fight to explain why the non-drinkers of our party were also passed out) and now we are all waking up. 

I think the DM would rather just move on from the whole thing, a big ol retcon.
