I was also going to mention this, and since I took the time to dredge up the pages in question here is the chart of possible reading times for everyone's entertainment:

Less than 10 min. Time for an employee conference and possible attitude counseling.

10-14 min. Keep an eye on this employee; may be developing slipshod attittide.

14-15.61 min. Employee is an efficient worker, may sometimes miss important details.

Exactly 15.62 min. Smartass. Needs attitude counseling.

15.63-16 min. Asswipe. Not to be trusted.

16-18 min. Employee is a methodical worker, may sometimes get hung upon minor details.

More than 18 min. Check the security videotape, see just what this employee was up to (e.g., possible unauthorized restroom break).

Notice, of course, that the only winning move is not to play. As usual this is all eerily prescient, with he only quaint thing about all of this is that Stephenson apparently thought that surveillance camera video would still be stored on tape in the future.
