Mr Frosty here too! Have never had one but repeatedly read as an adult they are shit.
I was also desperate for one of those Cadburys chocolate mini vending machines but never got one. I think in my head I had it imagined as some amount of huge endless chocolate instead of something tiny I’d have eaten the lot of on Christmas Day.
I also nagged for action man but got instead action girl (not very forward thinking mum who disapproved of girls having boys toys). Action girl was annoying as she didn’t have the posable limbs so there wasn’t much action about her and her boobs got in the way. I wasn’t allowed meccano or a garage, despite much nagging, for the same reason.
I did have a Girl’s World, though, which I loved. And a toy post office which was great. So it wasn’t all bad.
