Why was the General...? spoiler

I love this movie, and I try not to be too picky about things that seem unrealistic, but a thought came into my head as we were watching this last night. The General is surprised by the crowd, but there would be just too many indicators of a crowd of this size.

I would say there were literally hundreds of people in the audience. How did they all get there? Those that drove had to park somewhere, and if they took the train the small town taxi could not have handled all of them. Even if they took busses it would take a dozen trips.

Also, the crowd would be noisy, need to use the bathroom, and wander out into the yard or the inn. Plus, they are all drinking, surely the General would have an idea that his bar was being strained to the max.

I know I'm nitpicking but this is the most unrealistic part of the film for me.
