Where I play on rec-days there are two or three types of surrenders:
The optional one where you ask if someone wants to surrender - perhaps there is some doubt.
The none optional one where I tell someone they are out because they are out.
The none optional one where a ref calls a player out before the shot is made. Because of how teams fail to plan they often end up wit some kid guarding the flag station. All the "good" players from the other team defeat all the good players from his team in the center of the field and then charge. Once one gets into a position where they are going to bunker said kid the refs call him out.
