there is no way that two people should ever sit and wait for 3 holes then proceed to tee off when the group behind walks onto the tee.
Think you have miss read the op. They waited whilst they played their second, third and fourth shots to the fourth hole, and then teed off the fifth. Five minutes waiting at most. I assume they were not waiting for a group in front to get out of range.
Not sure why AmateurSwinger didn't just ask politely if they could play through. It may have saved all the aggro.
