This role play is to observe the decision and emotion after they are sick. The traveller was put into an contradiction situation as he need to go to watch a football match while he is very sick that he need a lot of rest.
during the role play, the traveller seems have no choice but to see doctor after he is sick. therefore, the football ticket become useless. this inspire me of something like online exchange tickets, sell the ticket to others, report to the insurance company for claims. Therefore, traveller can have some money back even he cannot watch the football match after he is sick and need rest.
See how the couple will react if one of them, the wife, is sick when they are in a hurry.
