When was it ever dangerous to others?
I would say chapter 2 page 43 and onwards. Although it would be more interesting if she didn't take initiative without her costume because she really didn't care about Crest getting punched and Orransong getting stabbed. But that doesn't seem in character for what we've learned of Maytag, the girl who can rescue anybody from any situation at the mere cost of her own health, either.
This scene is the one that pops immediately to mind; however, I'd honestly have to reread the archives to answer this (something I won't have time to do until my weekend).
That being said, the guy in the last panel claiming "Good show!" bothers me. Maybe, *maybe*, for someone who has already shown interest in, and has a history with, Maytag it could be somewhat interesting (as it is for the readers), but looking at it objectively... If I were some random person who went to a bar/club/whatever to see an entertainer contest, this just wouldn't be entertaining. I agree that the rules never said "funny" specifically, but I would just be sitting there going "um, wtf just happened? This is stupid/weird..." I'm really confused as to how she intends to win based off of "Teehee strangers I like to pretend I'm shy so people like me ^_^"
