wow, I can't believe you would concider not running the teen flicks to keep them away!! Thats abandoning your most profitable customers..teens may be a pain at times, but they sure spend up big!!
If it was me, I would get in a few more ushers who would keep them in line..We find that you only have to boot kids out once or twice for the message to be passed along to their peers that the cinema people won't stand for kids messing about anymore, then once the message is received, cut back the ushers a little and just keep checking them during the evening. We have very little trouble with teenagers here. You always know more young ones come in the take the place of the ones who already learnt their lesson, so you have to remain consistant. Our policy is
1st time- ask nicely for them to concider other people and be quiet/sit down etc
2nd time- warn them that they will be asked to leave if anyone has to speak to any of them for any reason whatso ever..and all will be asked to leave, not just the perpertrator
3rd time- ask them to leave. they will no doubt whine and carry on..but you just remain calm and firm and tell them you gave them fair warning. If they refuse point blank to leave, tell them you are calling the police and do so. Usually they will have left by the time the cops arrive. You can also just get the film stopped. Depending how bad their 'crime" is. Give all the other patrons a free ticket and continue the film at your descretion
