Yup. When you are told to get your hat and coat and follow the guard to the front doors, you probably have been sent packing.
The protagonist and new president, liberal Frank Underwood, was upset with someone in a meeting.
After the meeting, the president's chief of staff walked up to the person the president was mad at and was told his services would no longer be needed. Effective immediately. As in now.
The guy was shocked but said he just needed to get some things out of his office first and the chief of staff replied, "You're leaving now. Security will escort you to the door. We'll pack up your things and leave them on the sidewalk out front for you. Bye."
Talk about sending them packing. Pretty strong statement about your boss' displeasure when he fires you that way.
Not just, "You're fired" but "You're fired and oh, by the way, get out of my sight this instant you fr*cking, lowlife weasel."
