I marshalled at SPC in Shotts and then managed/ran the Wargames Centre in Ayrshire for 4 years for the owner. It’s not easy, you try to be fair, make sure the game brief is understood, make sure everyone is safe and deal with real issues, and as long as the marshal team pay attention (not staring at phones), everything else is really up to the players.
You’ll never please all of the people all of the time. Some folk thing they are Jonny Concrete with laser shots, others can start the quiet rumours that someone isn’t taking hits, then it spreads like the flu and you need to get right into the skirmish, which hurts, to ensure everyone is playing fair. It did sour my view of some players, but also there are many moments where your faith in humanity is restored..to a degree 😂, when you get a genuine ouchy or safety issue or just congratulations for great shooting or gamesmanship.
There’s generally many more good guys than dickheads, and you just need to keep a level head.
