Anyone who has watched a game of amateur sport has experienced a slightly annoyed manager/referee trying to usher fans to step back from the pitch before they start inching their way back to where they were standing.
It's just one of those facts of life, that people want to get close to the action to have the best possible view of what's going on. Nothing ever happens from standing to close does it?
Apparently it does:

Ouchie.
Looks like a great finish for the try all the same too.
