It was Night of the ad eaters on Friday and Saturday in Prague and you can see two necessary things here: the wristlet to access the cinema and the hand to shake after each ad (or to shake it in the rhythm of the ad's music :). They were playing this 6 hour marathon on all 10 screens of Palace Cinemas cinema simultaneously without a pause... only that there were a minute long "ad" for pause and when almost everybody went out the "ad" ended and the screening of regular ads continued. Well, we used it to go and see the accompanying program of the night. So no complains.
