See I can restrain myself from having a cigarette in a queue, if it's a long queue I just light up as soon as I get out of the bloody ride. It's actually not that hard to wait, you get a little bit agitated and might snap at someone (btw perfect time for a queue jumper is when I haven't had a cigarette and its a long queue) I don't see why they have to light up, it does make queuing unpleasant and personally for me makes me want one even more.
