Though M-time cultures tend to make a fetish out of management, there are points at which M-time doesn't make as much sense as it might. Life in gen- eral is at times unpredictable; and who can tell exactly how long a particular client, patient, or set of transactions will take. These are imponderables the chemistry of human transactions. What can be accomplished one day in ten minutes, may take twenty minutes on the next. Somedays people will be rushed and can't finish; on others, there is time to spare, so they "waste" the remaining time.
