Am I correct in believing that "quick line outs" are only allowed if the ball thrown in is the same ball that went out of play, to stop players grabbing any ball from the nearest ball boy?
Reference player conduct, rugby is on an entirely different planet, to football.
Small towns/villages will have rugby teams of all age groups and a social club, which has rules of conduct displayed on the wall, which include barring from all club activities for various offences, including insulting/swearing at the ref. And that is just the fans!!!
The elders, as in the retired players, that still frequent the clubs for games and social activities, help keep the young'uns in check, and supporters on the sidelines, aged 50+, will often point out errors made by a young, spotty, barely out of his teens ref, in a polite way and by calling him "Sir".
As a football fan, who spent a couple of years watching Syston RFC, (near Leicester and the home of Pukka Pies) it was quite an eye opener.
