I've always found it really interesting how other people serve their food. I've never really experienced anything BAD (other than perhaps my first meal cooked by now DH when we were at uni), but just different to what I was/am used to.
E.g. my dad will always serve up foods into a small buffet if he's cooking for anyone more than just himself (even if he's making homemade breaded chicken and chips, he won't plate up EVER, always puts it in bowls on the side in the kitchen and starts a buffet line - even if its just the 3 of us). Even when cooking for just him and my step mum, he'll decant the chips or rice or whatever the 'side' is into a large bowl. I understand not wanting to serve too much, but why can't he ask as he serves? Just to create extra washing up? I don't know, he didn't do it when I was growing up (but we also didn't have a dishwasher).
My friend of mine had 5 siblings, and I loved going to her house as a teenager, as there always seemed to be so many options for dinner. There were always extra friends, grandparents, etc over so there were often 10 or more people to feed and there'd be such a mix of food on the table. I think leftovers would just be bought out at the next dinner as there wasn't enough to served everyone again. Large boxed salads, a bowl of sweetcorn, a bowl of peas, a lasagne, herby potatoes, mashed potatoes, sausages, shredded roast chicken, jug of gravy, half a fish pie. As an only child of divorced parents I LOVED IT, as my houses were very "you eat what you're given" and were just me sat alone as parents ate later.
