People have to remember that the price increases have affected these businesses too and more so. Business utilities are uncapped so a small takeaway could have seen its annual bill go from under £10k to £50k+. Then there's the huge increase in the price of cooking oil and basic ingredients.
If it was providing annual salaries for a couple that's their income gone unless they increase their prices to cover it.
On portion sizes, if we're being honest, a standard meal of a main, rice and side like onion bhaji or spring rolls is far more than most people will eat, even for a treat meal, it's not 'competitive undereating' to make a takeaway last more than one meal, this is an enormous amount of food.
So many won't be ordering a whole meal per person, especially when feeding DC, which is why some orders seem 'cheap'. People will be controlling the cost by ordering the right amount of food and sharing dishes rather than a whole meal and sides per person and over eating or having lots of leftovers.
We're certainly being more mindful about takeaways, making sure it is worth it to us. So sometimes getting supermarket deals instead or sharing dishes, or using microwave rice (Waitrose pilau or egg fried is especially good and about 70 p instead of £3 at the takeaway).
For anyone buying naans, Costco have packs of excellent ones that work out at about 50 p each for a large garlic and coriander one. I've also seen the same brand in supermarket s where they're about £2 for 2 but either way, far cheaper than the takeaway.
