| # Coffee shop scenario | |
| Background: *This scenario is from a self-service ordering touchscreen at a coffee shop that you are assigned to develop. Jill is a customer who wants some coffee.* | |
| Jill starts to order some coffee at the touchscreen. She adds a small, dark roast. Then | |
| she adds a large medium roast with double almond syrup. She adds a | |
| medium medium roast with two soy milk shots (the second one by | |
| accident). She reads the price and it's too expensive. So she removes | |
| the second coffee (the one with the almond syrup). Then she realizes | |
| the third coffee has two soy milk shots and she removes one. The price | |
| looks good, so she submits the order. |
