1. You are standing in a single queue to a "cashcard" machine, which can perform only a small number of very simple and similar tasks. Using Kendall's notation, how would you model the behaviour of this queue? [Hint - this is a discussive question with no "correct" answer-expect you to draw out what the assumptions you make to fit an queue model. Is it really an M/M/1 queue?] How would your queue model change if you went inside to gain service? Again, use Kendall's notation and state all assumptions made. [Hint - inside.. limited space to wait, what would human behaviour suggest]
