As the credits are rolling, we hear the guy who was sitting in front of them SCREAMING at them. Along the lines of: "Are you fucking serious? You have no manners. Where were you raised?" ...he continued to yell at them for at least a few minutes.
Why the hell did the guy wait until the end of the two hour movie?
Would you ever yell at strangers like that?
What would you do if you were being yelled at like that?
