Isn't this the kind of mentality that is 'dangerous'?

"Why vote, I'm just 1 vote. It's not going to make any difference."

And you said you're not important enough that anyone would have noticed? So all the 'unimportant' people, when faced with difficult choices, should just roll over and go with the flow? (Not saying you made the wrong/right choice, but your reasoning is off.)

While you had to weigh a group of students' benefit from the talk against 1 missing out on some talk, this also could've been an opportunity for you to teach your students to a different kind of lesson.

I hate to say it but leaving a student alone waiting is pretty shitty.

I agree. This is the place to take a stand. It seems minor and annoying, but when we overlook minor violations like this, they soon evolve into major ones.
