I've had these particular scenes in my head for years but I'm curious as to what movie they came from, I must have seen it at least 15 years ago.
If a henchman messed up in someway he would be summoned to the boss' large office. The boss would be flanked by other henchmen and there would also be tarpaulin laid on the floor. He and the boss would have a brief discussion after which the boss would shoot the henchman. The others would then wrap him up in the tarpaulin laid on the floor and take him away. This left the office nice and clean after the bloody execution. Being called to the boss' office when it is set up in this way meant certain death.
There was a scene later in the movie where someone was called in to the office (same setup, tarpaulin on the floor) but after their discussion he instead gets to walk out. I think he was given an opportunity to correct his mistake or came up with some useful information.
