Participants are asked to walk to the counter through a virtual fastfood restaurant and place an order. The participant can select his preferred meal and decide if he wants a sidedish of fries or salad. There are two conditions: fries as the default sidedish, or salad as the default sidedish. Participants are being asked if they would like to change the sidedish to the other option. Also, the sidedishes of the other (virtual) guests can be manipulated to change the ratio of fries to salad.
