I've always hated milk puddings. And of course, you were practically guaranteed one a week for school lunch back in the 70s.
I refused to eat them. So the dinner lady would get the jug of rosehip syrup and pour what seemed like galleons on top, saying "this will make it taste better". No, I have rosehip syrup, too.
So, they tried the "you'll have to sit there until you eat it". So I sat there until the end of the lunch break, not eating it. Teacher had to come and collect me from the dinner hall, she wasn't happy.
This happened several times, and eventually one of the dinner ladies took it upon herself to force feed me. Didn't end well, I puked it all over her.
Told mum, she wasn't happy. Result was I got an apple for dessert whenever the milk puddings were on the menu. Can't quite recall the whole story, I was 5, and mum is sadly no longer here to ask.
