In Finland, grabbing the wrong basket can change your afternoon. Some supermarkets have started offering pink baskets for people who are single and would not mind being approached by a stranger between the shelves.

No one forces you to take one. But if you carry it, you are sending a silent signal: I am available to chat. And here is the curious part: there is an unwritten rule that everyone respects even though no one has written it down anywhere; people only approach others who are also carrying the pink basket. This avoids awkward rejections and misunderstandings, which are common on dating apps.

The idea started in just a few stores, but it has already crossed borders. Thousands of people on social media are discussing it as a more human alternative for meeting someone, without screens or filtered profiles. Perhaps the future of dating is not on a phone, but in the dairy aisle.
