A and B have had a day out planned for a few months. Day out is a 2 hour trip away and the opportunity for their children to have lunch at a place that sells food they can not get anywhere near where they live. Children are really excited about this. C had asked to join trip last minute which is fine, however, C and children will not eat the food served at this place and has requested they eat at a chain restaurant which they can have in hometown. A and B have said no, kids have been looking forward to this for ages, however if C and kids want to eat somewhere else then that’s fine and they can meet again after. C is mad and saying they are being selfish and not accommodating her palate. A and B refusing to budge as they had trip planned months in advance.
Who is being unreasonable?
