I have chosen case study 1 for this research. This case study is about two friends planning a party on a large scale for their immediate family and friends. For this party they need a venue that can provide food and have the safety to hold a lot of people. They wanted to serve alcohol. Mark found one venue that was good and with a fire safety capacity of 50 people. But this is also a kick back that if more people attend the event, the more discount they will get on rental price. Joe, the other friend was unaware of the financial details and discount and also about the safety. Both of them calculated the people they were going to invite.
