The £1 vending machine habit

Somewhere in the middle of going through a year of transactions category by category, one line item showed up more often than almost anything else in the whole export: the vending machine at work, roughly a pound a time, forty-something times over the year. Total cost: somewhere in the region of £45–£50. In isolation, it's the least interesting number in this entire blog.

Where it actually came from

It's a Pepsi Max, most afternoons, somewhere around the point in the day when the coffee's worn off and there's still several hours left. I didn't plan it as a habit. It just quietly became the thing that happens when I hit the afternoon slump at my desk — cheap, close, and fast enough that it doesn't cost any real time either.

Why I'm not going to "fix" this

The risk register post already made the argument I'd make again here: about 20% of your decisions drive 80% of the outcome, and agonising over the small stuff costs you something real — attention, and the sense that any of this is meant to be enjoyable — for approximately no benefit. Forty-something pounds a year is not a lever. It's not going to move a savings rate, and treating it like it might is exactly the failure mode that piece was warning about: mistaking something frequent for something that matters.

So this isn't a "look how I cut a bad habit" post. I added it up because I was curious, not because I intend to do anything differently. I'll have the Pepsi Max tomorrow afternoon as well.

The bit actually worth paying attention to

The number I don't have is more interesting than the one I do. Forty-something afternoons of reaching for caffeine and sugar on a schedule isn't really a spending question — it's a fairly reliable signal that something about the afternoon energy dip is worth looking at directly, whether that's sleep, workload, or just how the day's structured. That's not a line item a budgeting app can categorise for me, and it's the one thing this whole exercise actually pointed at.

Not financial advice — I'm not qualified to give any, and this one barely qualifies as financial content at all.
