At a recent dinner party in Shoreditch, a crime was committed. It was not a theft of cutlery or a misappropriation of wine. It was the crime of the equal split. A friend, who will remain nameless, ordered a starter, a main, two glasses of sparkling water, and a shared dessert. The rest of the table, who had gone for the tasting menu plus a bottle of burgundy, found themselves staring at a bill divided by party size. The victim? The diner with the modest order. The perpetrator? The group, aided and abetted by outdated social norms and, notably, by technology.
We live in an era of quantum computing, digital sovereignty, and artificial intelligence that can generate Shakespearean sonnets. Yet millions of us still divide restaurant bills by the number of people at the table. It is a brute-force algorithm in an age of elegant, personalised solutions. And the result, often, is a small but real injustice, a tax on the abstemious or the simply less hungry.
Enter the etiquette expert, the gatekeeper of social grace in the analogue world. Their latest guide, aimed squarely at the awkward diner, suggests gentle phrases: 'Would anyone mind if we go through the bill item by item?' Or: 'My treat, but let's do separate bills next time.' These are tools from a pre-digital age, verbal hacks for a fundamentally human problem.
But we can do better. As a Silicon Valley expat who has seen the future, I argue that the problem is not our manners but our payment infrastructure. The user experience of group dining is broken. The current app ecosystem offers some hope: Splid, Tricount, and even the built-in sharing features of banking apps. Yet these still rely on manual entry, human honesty, and a post-dinner conversation that can be as awkward as the bill itself.
Consider the alternative: a contactless, AI-powered system that learns your dining patterns. A restaurant POS that, at the end of the meal, offers each diner their exact share based on what they ordered, with a single tap on their phone. No more mental arithmetic, no more disputes over who had the extra side of chips. This is not a distant fantasy. Japan already has vending machines and QR code ordering that tracks individual consumption. Some London restaurants are experimenting with table-level accounts. The friction is dissolving.
Yet we must pause. The surveillance state also loves tracking. The same system that perfectly divides a bill can also log your preference for truffle fries and expensive Bordeaux, selling that data to marketers. The 'Black Mirror' consequence is a world where every bite is recorded and monetised. Digital sovereignty becomes digital serfdom. We must demand technology that empowers the diner, not the corporation.
So, friends, awkward diners, and etiquette enthusiasts, here is my advice. First, support restaurants that offer individualised billing. Second, use apps that store your data locally, not in a cloud controlled by a faceless algorithm. Third, and most importantly, remember that the awkwardness of discussing a bill is a small price for the intimacy of a shared meal. The human connection is the true algorithm we must protect.
As for that Shoreditch dinner, the victim paid, smiled, and swore next time to bring a calculator. I prefer to bring a better system. Let us build one, together.
