Ok, community story area, that makes sense.
As for my thoughts while reading the passage, it's just the technical side of me, which notices details like tense switches sometimes. And I wasn't sure of the reason for that particular spot. The switch to present tense overall is fine. It puts in my mind, the sense that the storyteller is leaning in toward his audience, perhaps whispering, or perhaps a more hurried pace. And then in the fine paragraph where it goes back to past tense, he's now backed away again, and is speaking broadly and louder, again to his audience and beyond.
