yeah i thought so too and honestly i have been planning to do it since i have been allowed to watch movies by myself. And that was what.... many many years ago. The only thing that prevented me is the thought that if I got caught (if ever it is not allowed), it would not be worth it.
yup, it may be very obvious but come to think of it if there is no rule posted anywhere, how would one know? we cannot all 'assume' that everyone has the conscience and not do it, right?
after so many years and so many movies and different theaters, i noticed other people do it. And even up to this time i cannot find anything that says it is NOT allowed. they should put something up like a sign somewhere like in the ticket booth. i mean common sense is pretty much NOT that common at all.
This is suspect reasoning. You can't justify doing something wrong because you've determined that it is conceivable that someone -- someone other than yourself, in this case -- might not know its wrong. That gives you deniability if you get caught and choose to lie; not moral authority to do it in the first place.
Anyway, I'd be shocked if there were nothing anywhere about theater-jumping, but you don't need an explicit sign to know it's against the rules. Why else would you buy a ticket to a specific film? Almost every theater I've ever been to has had the name of the film printed on the ticket, as well. That's pretty explicit.
my take is, the movie theater people (owners and those working in cinemas) know this. I think they just do not bother (depends on which cinema you go as jrs has said) because (i assume) they make their profit anyway.
"Make their profit"? Profit is not a binary switch. You can make more or less. Anyway, I'm sure plenty of employees are lax about security. But security is lax in all sorts of places. Whether or not a theater has factored illegality into things is irrelevant when determining whether or not its okay to do it. I'm sure convenience store owners expect a degree of theft, but that doesn't make it okay. And speaking of which, have you ever seen a convenience store with a sign that says "Don't steal anything"?
come to think of it, why would you design a cinema in such a way that people can just transfer from one movie to another? and to make it worse, tickets are collected at the main entrance and no signs saying that you cannot move from one to another.
They probably believe (rightly, I'm sure) that it costs more to put ticket-takers at every entrance. And when you think about the structure involved, I have to imagine a theater which broke off into different areas -- one per movie -- would prove impractical and expensive in comparison. Most theaters, then, have likely decided that the cost of fraud is dwarfed by the cost of irregular construction and/or extra hours for ticket-takers.
It's clear you're looking for moral wiggle room, but there really isn't any. You know it's wrong, or else you wouldn't have even asked, to my mind.
