sentences:  For example, consider running a call center.It may be more effective to have low cost call center operators wait for 
  high value clients rather than risk losing high value clients by making
  them wait.Given the asymmetric cost of these errors - particularly if
  the processes are not smooth - it may be prudent to have what seems like
  a surplus of call center operators that appear to be "wasting" call center
  operator time, rather than commit the higher-cost error of losing the
  occasional high value client.
