Go to places like the USA and see a nation of people seemingly unable to form a queue without needing to eat something. Sadly it looks like we too are heading the same way.
Everything we do in the high street/shopping/festivals/events is becoming about food and snacks now.
Take Cinemas - 30 years ago you might get people taking a small bag of sweets in, anything more than this was highly unusual, ice creams in the intermission excepted of course.
Now you can't move for people chowing down on nachos, hot dogs, pizzas or burgers.
And yes, childhood obesity, obesity in general in this country and some others are off the charts, and all of that is down to a change in eating habits, junk food being more accessible to people than more healthy options, processed food being pushed at us for profit.
When my DS was in primary I would take the occasional snack but I was very conscious that I didn't want it to be an expectation, and for him to form a habit that I then had to uphold, it would then become a JOB I had to do, rather than what it was, an occasional surprise.
That said, if we had to go to an afterschool class, swimming or music or whatever, it was impossible to do without a car picnic. but that was specifically because I knew it would be 2 hours poss 3 until he could have his proper 'tea'.
It's not stopped him wanting snacks, and now he's older he still will make crap choices if given free rein, but that's what happens, I have to make sure that what I buy is sensible, that junk is not off limits totally, but managed sensibly. I'm not saying i have it right, but its an attempt at a conscious thought to what's going into his mouth.
I think what OP is referring to is the snacking of kids who live 3mins down the road and getting automatic snacks... and yes it does happen, we ALL know this. It's the same kinds of kids who melt in the rain.
OP is trying to understand the nonsense that is the british schoolgate, wondering if being foreign could explain why she couldn't. I didn't take it as a "oooh look at zeeze eenglish, what are zey like" kind of thing.
Infomerkel It's not you love, nothing about the whole school/schoolgate/playground stuff makes any sense. Welcome to the alien planet that is the School System
