2. Fish and chips were served in newspaper until the 1980s.
Serving fish and chips in newspaper kept prices low, but in the 1980s it was ruled unsafe for food to be touching newspaper ink. Now fish and chips are wrapped in a layer of greaseproof paper, and then a layer of newspaper if wished.
3. Not all fish and chip shops serve vinegar.
You’re more likely to see non-brewed condiment behind the till. Non-brewed condiment is acetic acid mixed with colourings and flavourings, and is quicker to make than vinegar. Due to UK Trading Standards it can’t be labelled as vinegar, or even be put in vinegar bottles.
6. There is a long tradition of funny chip shop names.
7. Over 250 million fish and chip meals are sold each year in the UK.
