How a refund dispute turned into a Wuhan coffee enthusiast movement

Instead of hurting business, the case drew local coffee enthusiasts and out-of-town tourists to the affected shops, and some shops launched a same-style drink that helped traffic rebound.

Last Sunday, a story that was both amusing and exasperating spread through Wuhan's coffee community: a customer nicknamed "Allergy Sister" by netizens successively demanded refunds from 41 coffee shops on the grounds of experiencing allergic symptoms after drinking. After the matter escalated, multiple coffee shops that suffered losses have collected relevant evidence and jointly called the police, demanding that the person involved publicly apologize to these affected shops.
According to follow-up reports by local media, Wuhan's local coffee enthusiasts are quite angry about this matter. After figuring out the whole story, many felt sympathy for the shops that were claimed against by "Allergy Sister" and took the initiative to consume at the shops to show support.
Out-of-town tourists who learned about this through various social media platforms, out of sympathy or curiosity or other mindsets, added Wuhan to their May Day holiday travel lists, traveling great distances just to drink a cup of "Allergy Sister's Same Drink."
To help tourists identify and check in at these affected coffee shops, enthusiastic netizens have compiled guides such as the Wuhan Coffee Shop Allergy List and the Wuhan Affected Café Map. Some lists even carefully note the allergens contained in the drinks, reminding those who try them to watch out for risks.
Many coffee shops that had self-verified being visited by "Allergy Sister" have also, at customers' request, put "Allergy Sister's Same Drink" on their menus, and the shops have posted particularly eye-catching promotional posters. Some restaurants not affected by the allergy incident also want to ride the wave of hype, using posts like "Thank you, Allergy Sister, for not drinking at our shop" and "Allergy Sister, is our shop not worthy?" to attract attention.
As local coffee enthusiasts say, "Allergy Sister" not only unintentionally brought about a collective team-building for many coffee shops in Wuhan but also added a "Coffee Allergy Festival" to the city that requires no organizer or planning.
This shop-visiting and check-in activity themed around "coffee allergy" has brought enormous traffic to Wuhan's coffee community. Some coffee shops that originally had sluggish business gained attention because of it, and sales of "Allergy Sister's Same Drink" in the shops surged, becoming the hottest-selling product recently. Some coffee shop owners admit that orders have increased considerably recently, and sometimes due to ingredients running out, they have had to temporarily close delivery channels and restock.

A shop owner who had originally planned to close in June said he didn't expect to gain so much online attention because he had compensated "Allergy Sister." The small shop used to rely mostly on nearby regular customers, but now it's bustling, and sometimes customers can't even find a seat when they come. The unexpectedly huge traffic has brought customers from all over to the shop and made business improve exponentially.
However, the owner also admits that he understands the current popularity is only temporary, and whether the shop can use this to convert shop visitors into returning customers is still hard to say. As for whether to change his mind and keep going afterward, or wait until the incident's attention fades and close as originally planned, the owner says he still needs to wait and see for a while.
After all, shop owners all know clearly that for a shop to operate long-term and make consumers recognize its brand and various products, relying solely on the popularity and traffic brought by one "Allergy Sister" is far from enough.
