Many live PA rigs are run in (dual) mono simply because the stereo image, if there, would only be audible those in the the audience seated in the middle of the auditorium. Those seated to the right would not hear things panned to the left and visa versa. And yes, even if the rig is running stereo, and you have seats in the central part of the venue, the stereo spread will be much wider close to the stage and will more or less disappear long before you reach the cheap seats.
