A Coffee Shop Refuses Service to Children Under 12, Unless...

Can you recite pi from memory? Most people's recall stops at 3.14; the more gifted might get to 3.1415926, leaving the rest to calculators.

A coffee shop in Taiwan called "Migratory Bird Exhibition" has an unusual house rule: "Children under 12 are not served—unless they can recite pi to 30 decimal places."

Controversy and Debate

The rule ignited heated debate online. Some asked whether refusing service to children counts as discrimination.

Others shot back asking whether the owner could recite pi themselves, arguing that a good memory has nothing to do with self-control. By the same logic, adults should have to pass the same test to enter—otherwise the rule looks like it exists purely to make things difficult for children, and the indirectness feels like a way of humiliating them.

But the critics were in the minority. More netizens supported the shop, praising the owner: "This tests adults as much as it encourages children," and "I like rules that let you prove yourself—it creates a fairness that doesn't eliminate possibility while avoiding irresponsible situations later."

The Unique Coffee Shop

The shop sits in Taipei, Taiwan, and stepping inside is genuinely spectacular: zebras, giraffes, peacocks, warthogs, plus impalas, Atlantic puffins, wildebeests, and dwarf antelopes only a zoologist could name—more than a hundred specimens, large and small, preserved in their most lifelike poses for close observation.

According to reports, the antiques, specimens, and vintage books on display are all expensive; the priciest specimens run into six figures. The giraffe specimen alone costs 600,000 New Taiwan Dollars (about 136,200 RMB).

The owner is candid about it: "We don't trust the self-control of all children. The specimens and antiques in our shop are expensive to make, and any damage would create an awkward situation."

The Pi Challenge

Still, the manager says they don't want to close the door on children proving themselves. Hence the rule: children under 12 may enter only if they can recite pi to 30 decimal places. The shop even thoughtfully provides a cheat sheet: π = 3.1415926535 8979323846 2643383279. They note that children under 15 have memory capacity 1.5 times that of adults. So far, two children have successfully recited 30 digits and dined inside—one aged 6 and one aged 10, each needing about an hour to memorize.

Perhaps the rule isn't just about protecting the shop's expensive treasures—it's also about protecting children who can't sit still. These specimens are exquisite; forget children—even I'd be tempted to touch them up close. What do you think of this "genius assessment" rule?
