Well, at the start of a new term, (particularly a new year) I think it's expected that some people's circumstances will have altered and so there'll be some changes. Our newsletter today just re-iterated that you can't change from one to the other mid-term, because of the kitchen bulk-buying in advance etc... People still do, however.
what can I say, Intolerant??? - that we aren't happy with the shit they are serving? I did speak to them 3 times last term about them serving chips apparantly every fecking day (there's no choice at ours, just one meal)
You don't have to give any explanation. Just say (or write a note, if you're not feeling brave enough!) saying that dd will be having packed lunches this term with immediate effect. It's not as if you've signed any legally-binding document.
we blamed dd's whims... " Mrs Scary Secretary S doesn't want dinners any more, we really did try to convince her but, to no avail" The little sod dobbed us in later, so prime/bribe/blackmail her first.
Our school office get narked when people change without informing them. So they send a bill for lunches unpaid for, and the parents get narky back and say, "but they've been having sandwiches for weeks." But the kitchen didn't know, and have been providing (and paying for) meals that have gone uneaten, unbeknownst to anyone. So the school loses out financially. At least you'll be telling them your plans. And don't let some arsey woman in the office scare you into paying for something you don't want. Do you really want to pay out a couple of hundred quid just so you don't have her glare at you? Go on, take her on!
We prepay online, so I make a payment for a few weeks worth of lunches and it's electronically deducted each day. But because it's quite a big school, they like to know that x pupils will be having lunches that week so that the canteen can cater accordingly.
