Suppose that we test a discount system in some e-shop. The system can send a loyalty card to a client and admit a discount of 0% (no discount), 5%, or 10% according to the following rules:

• “No discount” is the default discount option.


• A nonregistered user has 0% discount by definition.


• If a registered user spent more than $1000 in the previous shopping sessions, and there were 19 or less shopping sessions, admit 5% discount.


• If a registered user spent more than $1000 in the previous shopping sessions and there were at least 20 shopping sessions, admit 10% discount.


• A loyalty card is sent only to registered customers who spent more than $1000 or had at least 20 shopping sessions.
