You can beat a gunman into submission - I’ll go along with that. You can’t torture him with hot soup, if what he alleges is correct happened while waiting for police to arrive. Neither can you invite the rest of the crew to put a boot in for the building of team spirit. That being said, he’s lucky he didn’t try this in a place where he was more likely to be shot dead the moment he threatened anyone with a gun.
Plus, it’s not easy being an armed robber named Nigel.
If he still had his gun or was still a threat, hot soup or coffee is appropriate.
