title: UML Use-case diagram postcondition implementation (with diagram)
body: <p>I'm learning UML by trying to simulate how a car service garage works with diagrams and documentation. One problem I have is with postcondition (or rather, GOTO) statements.</p>
  
  <p>Is the dashed line &lt;&lt; include >> relationship only for preconditions? Can Use-case bubbles connect to eachother and follow a logic path?</p>
  
  <p>So this is what I have so far..
  1) Is the 'Settle Payment' bubble in the wrong place? Should it have been &lt;&lt; include >>ed to the other bubbles?
  2) Should I associate the 'request service' bubbles to the technician too as he will be the one fixing the car?</p>
