This is just to have a couple of laughs.
Anyone who has ever read or studied something about wedding photography knows you should be super alert all the time. And not miss any important happenings and speeches. And probably not go around eating. And most of all, not to get caught while doing any of the above.
Well, this dude failed to obey those guidelines and ended up caught on film. Check his face when he realizes it!
