i have done this as wellI cautioned a player who repeated and agreed with what a player was getting cautioned for!!!
Player One should something like 'thats a f'kin joke decision, you've given us fuc all today'..... As I called him over to caution him his nosey mate asks him what he'd said, to which he repeats it all verbatim and then says, 'well, he's right and you have given us fuc all'....... Cue double yellow!!!
