Yes, I was fussy as a child and I'm still fussy but in a different way.
As a child, I hated the cheap foods my mother was obliged to buy:
Fatty gristly meat e.g. sausages with bits of bone and connective tissue, stewing steak we had to chew and chew till we nearly threw up, mince with white bits, bacon (although I dissected bacon and refused the fatty bits)
Nowadays, I won't eat anything with more than four legs or less than two legs, so I reject all shellfish. I do eat actual fish even though they have no legs 😂
Many people are amazed that I won't eat crab, lobster, shrimps, prawns, mussels, oysters etc. I can either plead allergy or just exert my right to make my own decisions but I do find a lot of sea food to be off-puttingly ugly on a plate e.g. octopus
I have tried some sea foods out of politeness e.g. scallops at dinner in a friends house. They were OK but nothing to write home about. I also tried a snail and a mussel when out for dinner with friends. Both were an unpleasant texture.
This has been an adult choice since shellfish were never on the menu when I was a child. My grandfather would eat cockles out of a jar, using a pin. Urrrr!
