Before advancing Current Time, we also record for this first customer upon entering service that
  1. its waiting time (excluding service) has been 0,
  2. its waiting time (including service) will be 1.76284.
Except for its service completion, we are done dealing with this (or any other) customer once it enters service and the above information has been recorded, so its arrival (A) then will be deleted from the time line.
Having recorded the desired information about the current performance of the system, we now are ready to advance Current Time to the next event, which is the second arrival.
