1) I have reffed 1 event, and more are planned
2) £15 mainly goes towards the upkeep of the site, which is more then fair. I find that refs aren't usually at these training sites, but the players that aren't playing usually marshall
3)Main problem - Inconsistancy, i have heard of bad calls been made at a few events, but its getting there, I find that arguing with a marshall is usually the wrong course of action
4) Take what you have a walk away in game, after the game, talk to the ref, express yourself by all means, this is how we learn what our mistakes are and how we improve.
I have personally made bad calls, but were all human and after marshalling an event I can understand how people can get calls wrong, you only have once chance to get the call right. Talk to the marshalls, don't yell to them, when we make bad calls we feel bad aswell - were here to make you day worth while, not to ruin it, we do feel bad if a bad call has been made.
