How does BigLaw bill a building evacuation? [Expensively, is my guess]

We had a Fire Drill at the office. In a 50 story building. With lots of lawyers.

When the fire alarm went off, I nearly soiled myself. But once I regained my composure and remembered the memo that “This is a drill.” I was not going to leave my office.

I was thinking to myself that if this were not a drill, I would have burned to a crisp in my office, hands clutching client files. But since this was a drill, I am just doing my work and debating about stealing other attorney’s office supplies.
