Bob is a very busy dude. He hates wasting time. He also hates obtrusive ads.
He buys a ticket for a movie which he really really wants to see. The ticket says: "Time: 7:00 PM". Sometimes the fine print may say that the theatre may play ads for 5-15 minutes from the ticket time before the main feature starts.
He arrives at the theatre at 6:59 PM and takes his seat, hoping to start enjoying the movie in less than a minute.
But instead, the theatre plays ads and movie trailers for 15 (!) minutes before the movie starts. It is not possible for Bob to find out in advance how exactly long those ads will play. Bob does not want to risk missing the beginning of the movie he wants to see.
Bob is very frustrated that the theatre stole 15 minutes of his time and filled his attention with crap. He would rather do some business instead and arrive 15 minutes later.
Is this market regulated in regards to this concern anywhere in the world?
Does Bob have any legal avenues (e.g. a class action lawsuit) to compel the theatre to specify the exact time when the main feature starts, and honour this time precisely?
