They still have a shelf in my chemist of tiny glass bottles of olive oil, castor oil, etc. Apparently people still buy the olive oil though I looked at the prices and went to the supermarket!
My parents were into healthy eating in the early 70s, so eating out meant Cranks cafe which sold weird hippy food like quiche and stuff with wholemeal flour. I got vitamin C daily, which came from a 5kg pharmaceutical brown glass jar, and a couple times I got to go with my dad to a back entrance at UCL and he'd hand some cash to his friend who ordered it in bulk! Bread came from Holland & Barrett along with ingredients for moooozlee, like prunes, but sometimes we'd splash out on Loseley ice creams from there. Thankfully my dad made mum promise never to buy carob anything ever again once I was about four.
Pick and mix at Woolies across the road was wonderful to see but I was never allowed any as it was expensive. Never had takeaway Chinese nor went to the chippy, but about once a year would go for a typical 70s curry. Mum worked near the original Pizza Express and the fourth opened in our town so we went there quarterly, back when it was amazing and good.
Mum fretted about dinner parties which she'd host every few months. Especially as we didn't have a freezer until the mid 80s (amazed how many had chest freezers in the 70s!). Starters were usually cheesy fish in real large scallop shells, and I'd have one for dinner and go to bed, then in the morning drink all the dregs of Bailey's in all the glasses. My parents were very square compared to most (or ahead of their time!) and not only didn't smoke but also didn't think drunk children were funny or cute.
We lived in a 1969 new build so there was an en suite shower and basin. Which were used the former for the laundry rack, in case of drips, and the basin when my dad did DIY etc.My dad had to test the shower in 1983 before we moved, and didn't see them catching on! Other people had bidets which invariably housed a large geranium.
