Re: Are you a stickler..
Most of my generation learned table manners by watching Pretty Woman!
We always used to sit at the family table as kids with a three course meal, fully set table, napkins and a tablecloth. My dad would say grace. There would be tea and coffee after pudding. It was the event of the day.
I can't remember whether it was at school that I first saw someone eating with just a fork, shovelling food in their mouth. I thought it was charming. I guess you just go with the etiquette your parents teach you as a child.
My pet hate is if someone talks with their mouth full. Puts you right off your food.
