I personally wouldn't think the Christmas fridges thread on here is the norm of what families eat at Christmas - at all.
Lots of people are having to tighten their belts for various reasons.
I live in an area of the west of Scotland where there are pockets in the town where people obviously have money - but a lot of people don't. Some people rely on food banks and community fridges. The community fridge I use does a meal for people at Christmas that they can pay 3.50 for and heat up at home.
They also do cheap meals weekly - pay as you can afford. And this year they did a sit down free Christmas dinner for people - because there's the need for it. Some people are poor and isolated as well
I have also lived alone all of my adult life - so it's pretty pointless for me to pack my fridge with 100 quids of stuff I wouldn't eat even if I could afford it
By the way - if people have 400 quid to a grand to spend on Christmas and enjoy it - that's completely fine
I don't think my family have ever spent 400 quid on a Christmas dinner in our entire lives - even when I was working full time and earning a lot more money - but I was veggie for 35 years and I've been vegan for 7 years now - so turkey dinners aren't my thing anyway
My gran was housebound for the last ten years of her life or so and my mum and I used to get a takeaway at her house on Christmas day so she would have company - sometimes the Christmas you have also depends on older relatives and going to visit them and the situation they are in.
I actually give to a charity in Scotland. They helped 17000 families at Christmas this year. A variety of people in need, women fleeing violence, people referred from hospital. You buy the present and the parent or guardian gives it.
Normally I buy for teens but this year I bought clothes for babies - I don't have much but a lot of people have much less than I do
The norm at Christmas can very much depend on a lot of factors in someone's life
