Who is being U regarding lunch?

[SidsWife]

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.

[Iusedtobeapartygirl]

C is being u reasonable. And a bit spoilt.

Enjoy your day out!

[Hiphopopotamus]

C! What’s the food?

[8by8]

C is welcome not to come. She wants to join a trip others have planned, she needs to join in with what’s already planned.

[poopbear]

C! Stick to the original plans. Somebody joining late should not be derailing the plans

[Finfintytint]

C is unreasonable. Kids can try something new for a change. I wouldn’t be dictated to like this.

[ConsiderTheCentre]

C of course.

[PurpleDaisies]

C is out of order.

[HunterHearstHelmsley]

C. They tagged along. Could they not eat somewhere else and meet again after?

[MaggieFS]

C, although I do wonder on the group dynamics. Would C normally have been invited from the start? Why the late invitation?

[CwtchesCuddles]

C

[Thehop]

Definitely C

Don’t change your plans.

[Finfintytint]

I’m trying to think of a food that I could only get with a 2 hour drive.
So for me it must be Ikea Meatballs

[Trahira]

C unreasonable

[katy1213]

How cheeky to invite yourself and then get mad! But I'd love to know the mystery food!

[MyCatHatesEverybody]

Cheeky fucker

[flumposie]

C. Do not change your plan.

[Edwardbear1]

C

[Knittedfairies]

Definitely C!

[recrudescence]

If someone joins this thread to make the case that C is being reasonable then I shall lose all faith in Mumsnet.

[MiniGuinness]

I can only answer if I know what the food is. If it is Ikea, then C is ridiculous and should be uninvited immediately.
