When the Swedish-furniture maker Ikea entered the Chinese market, the company probably wanted its new customers to feel right at home. Mission accomplished, though maybe not in the way anticipated.

Even more than shopping at Ikea, the Chinese love hanging out at Ikea. For years the company has turned a blind eye to that family chattering away for hours around the table in the mock kitchen, or that young couple taking an afternoon snooze on the display beds. After all, Ikea made 4.9 billion yuan ($766.5 million) in sales last year from its nine stores in China.

But now a matchmaking group for middle-aged singles in Shanghai seems to have taken advantage of Ikea’s hospitality, and the furniture giant is up in arms about it.

A Wall Street Journal blog post reports that for the past six months, two afternoons a week, a Shanghai Ikea cafeteria becomes overrun by a crush of local singles between the ages of 45 and 65. They are there to “seek out new love over free cups of coffee.” This being China, the crowd can reportedly swell to 700 people. That’s a whole lot of coffee.

The free cups of coffee are a perk of holding an “Ikea Family” membership card. Most of these singles are, you guessed it, card-carrying members. Ikea can’t touch them the events have become so intense that the Ikea branch has had to hire additional security guards and cordon off a special zone for these free-coffee-loving singles to keep them from disturbing other customers.

The store’s public relations manager told the Wall Street Journal that they have not been able to identify the organizers of the matchmaking group but was hoping to do so soon.

One of the sticking point for the company seems to be that these singles bring their own food instead of ordering a plate of Swedish meatballs. The store has reportedly put up a sign in plain sight of these lonely hearts that reads,” Bringing in outside food and tea violates the cafeteria’s regulations…If you are a member of this group, we feel we have warned you, do not use the resources of Ikea to organize events of this kind.”

Unfortunately for Ikea it seems, at least for the moment, that warning has been drowned out by the crowd.
