I can see that there are practical problems with delivery to the school, but I would be interested in the concept. I know that it is more expensive than making a packed lunch myself, but would be less hassle, and wouldn't have all the 'left lunchbox at school' problems either.
It would be cheaper than the school dinners at the dses senior school, as well as sounding healthier than any of the options open to them - school dinners, which are awful and not very healthy (they use powdered, dried cheese - urghhh), a burger van that parks just up the road, the local coop or newsagents, or the chippy. Sadly the school does not stop the kids going off site at lunchtime, except in Senior 1 (the equivalent of year 8, but the first year of senior school in scotland), and even they seem to be allowed to go as far as the burger van.
We used to have the Scotcard - a smartcard you charged up with a certain amount of cash, and which could be used in the canteen, but the machines were taken out almost 2 years ago, and have never been returned, so I have to give the dses cash - which they can spend anywhere.
If someone was delivering them a freshly made sandwich, salad, fruit and yoghurt for their lunches, I'd be very happy. They won't take packed lunches from home (and to be honest, I am too tired and depressed to fight it out with them to make them take packed lunches, not to mention too tired etc to cope with the stress of them not making their lunches, forgetting them, moaning about the choice of filling etc).
I am sorry this has turned into a rant. To be honest this is one of the areas I have given up in. I can't cope any more, and would love someone to be dealing with this for me.
