Sorry for late response!
It happens throughout a lot of sections of chapter 1, but I think it started when they arrive in Rotten Redd's Alley. So far nothing of the sort encountered in chapter 2.
I can't exactly remember if I skipped at any point, especially since I was doing a full reread of the game. However, knowing I have a habit of skipping with other Ren'py VNs (that I'm less invested in), I wouldn't be too surprised if I used it a couple times.
Hope that helps!
