title: SimPy Bank Tutorial with users lining up for a specific counter, and being able to leave the line early
body: <p>I'm looking at this SimPy tutorial <a href="https://pythonhosted.org/SimPy/Tutorials/TheBank.html#several-service-counters" rel="nofollow">https://pythonhosted.org/SimPy/Tutorials/TheBank.html#several-service-counters</a> and <strong>I am wondering how this could be changed to have customers use the same line but use a specific counter?</strong> <strong>And as a further modification, what if they did not have to wait to be at the front of the line to get to a specific counter?</strong> </p>
  
  <p>Background: I'm trying to simulate a line of people lining up to go to a theatre with set seats.  Everyone has to line up to get into the theatre itself, but not everyone has to wait for the guy in row 5 to be seated if they are in 6 or greater. And everyone has a set seat (much like a "counter" in the example). I really enjoy my local theatre but I am hoping to be able to simulate a much easier way for people to line up and find their seats.</p>
