You arrived after the appetizers were gone and the cocktails were empty. Somehow you're splitting their tab.
45 minutes late.
Split evenly anyway.
You missed three rounds. You paid for all of them.
The scenario
Traffic. A work call that ran long. Life happened. You show up 45 minutes into a two-hour dinner. The table has already ordered—and finished—two rounds of cocktails ($72), a cheese board ($28), and calamari ($18). By the time you sit down, you order a single entree ($26) and water. The bill arrives: $380 for six people. Someone suggests splitting evenly. That's $63.33 each. But wait—you consumed $26 of food. You're being asked to pay $63. That's a 143% markup on your actual consumption. You're subsidizing $37 worth of appetizers and drinks you never saw. Here's where it gets psychologically tricky: speaking up feels impossible. You were the one who was late. You feel guilty for making everyone wait. Asking for a separate calculation feels like adding insult to injury. So you pay the $63, silently absorbing the cost of your own lateness. But lateness and overpayment are separate issues. Being 45 minutes late to dinner doesn't mean you should pay for someone else's martini. The social penalty for tardiness shouldn't be a $37 cash penalty. Research on equity theory—developed by psychologist J. Stacy Adams in 1963—shows that people expect outcomes proportional to their inputs. You contributed less to the meal. You should pay less. That's not cheap. That's fair. And this scenario is increasingly common. According to the Bureau of Labor Statistics, Americans spent an average of 67 minutes commuting per day in 2023—up 8% from pre-pandemic levels. Traffic delays, unpredictable schedules, and remote work transitions mean more people arriving late to social commitments. The late arrival problem isn't going away.
The solution
splitty solves this elegantly. Scan the receipt. Assign the pre-arrival items—the cocktails, the cheese board, the calamari—to the people who ordered them. Assign your entree to you. Your share: $32.50 (your entree + proportional tax and tip). Not $63. The people who arrived on time and ordered drinks pay for their drinks. The person who arrived late pays for what they actually consumed. No guilt-driven overpayment. No awkward negotiation. The receipt shows who ordered what. splitty calculates who owes what. The math is objective. The outcome is fair. And here's the best part: nobody has to bring it up. You don't have to say 'I shouldn't pay for the cocktails.' The app just assigns items to people. Fairness becomes automatic, not confrontational.
