My total severance package from the company that laid me off was "we'll pay you until the end of the day." I had been there continually for nearly 8 years, and had worked there previously for another 4 1/2 years.
That day was spent calling my appointments, letting them know that I wouldn't be there, and filling in the other field engineers on what I was working on.

That was a "nice" thing to do for an employer booting you out the door. You could have given your customers your cell phone number and offered to contract them at a more favorable rate than your soon to be ex-employer. It's not like you were in danger of losing a big severance.
