#### Answer

\begin{array}{l}{\text { There are many other possibilities, but here are a few: }} \\ \\ {\text { a. The possibility of mechanical breakdowns. The model could be }} \\ {\text { designed to include the occasional breakdown of a critical component }} \\ {\text { (e.g., the French fryer) to study how the system responds to these }} \\ {\text { types of unexpected events. }}\end{array} \begin{array}{l}{\text { b. Rather than say no customer ever takes more than } 5 \text { minutes to }} \\ {\text { be served, the model could be designed to allow for an occasional }} \\ {\text { massive order-someone purchasing 100 hamburgers-to see what }} \\ {\text { happens to our waiting times when this unusual event occurs. }}\end{array} \begin{array}{l}{\text { c. Some servers could be used only for special orders, rather than have }} \\ {\text { all servers be identical. }}\end{array}
