If I were waiting in line for a character or something, maybe that would bother me... but an attraction? Not so much. It'll still be there.
Honestly, though, I've never noticed much line-jumping going on anywhere I've been recently.
It bothers me a bit when people take it upon themselves to punish linejumpers by "accidents" or purposefully moving slowly or whatnot. That seems very passive-aggressive to me and I don't care for it. Calling someone out is a lot more appropriate than 'getting back at them' for behaving badly.
