I hate headlines like this. You read the article and discover she works in finance, he runs a life coaching business whatever that is, and they retired once their savings hit £1 million which didn't come from making their own sandwiches.
Meanwhile out in the real world most of us have been bringing packed lunches to work since the 2010s at least and are still one unexpected vet bill away from a couple of months of home haircuts.

It has literally never even occurred to me to buy lunch out. To think that they've budgeted four thousand pounds of their salary on it is batshit to me. To a person on minimum wage that's over 16% of their salary. If you then removed travel costs that leaves a shade over 18k. Then energy, water, council tax, broadband and TV licence brings it down to under 13k. The average annual food costs for 2 people is 5k which brings it down to 7875, which means you'd need to find somewhere to live that costs £650 a month (less than half the average UK rental cost) then literally never go out or do anything. It's like me saying I've been buying a horse every morning to travel to and from work then just releasing it at the end of the day, but instead of 5 new horses a week I've decided to take the bus. Please shower me with praise for not purchasing approximately 253 new horses every year (average cost £4500 =£1,138,500).

@TheBreadmonkey @afewbugs I do buy lunch out but only because I am in the office most days. We have a canteen but I tend to just get a sandwich from Sainsbury's on the way in.
