“I understand people who don’t like us,” said Gareth Fletcher, a 27-year-old with a blond mop top from Gold Coast, Australia, who is one of the Fanatics’ tour guides in chief. “It’s all about tradition for them, and they don’t want anything ruining their experience. But at the end of the day, if I can’t stand up and support the players, how is there going to be any atmosphere at the matches? How do you create that?”

Wimbledon, it must be said, has done just fine without the Fanatics for more than a century, although it has certainly had its share of crazies through the years: Centre Court streakers and Jeff Tarango’s ex-wife Benedicte, who slapped the chair umpire Bruno Rebeuh across the face after a contentious match in 1995.

But the beer-stained set has generally been restricted to exceptional circumstances: the so-called People’s Sundays when rain delays in the first week forced an extra day of play on the usual day of rest at Wimbledon; or the memorable People’s Monday in 2001, when Goran Ivanisevic of Croatia beat the Australian Patrick Rafter in a rescheduled men’s final that felt more like the Davis Cup.

But the Fanatics are planning to keep queuing every night until Saturday.

“That’s what the queue is there for,” said Richard Lewis, the chief executive of the All England Club. “They’ve got plenty of passion.”

Jack Sock might be less pleased. He is a good friend to Kyrgios, his PlayStation rival and Chipotle dinner partner, but apparently no friend of the Fanatics.

On Tuesday, during his first-round loss to the Australian Sam Groth, he had exchanges with Fletcher and eventually struck a ball hard in his direction in the third set, hitting the low courtside barrier behind which Fletcher and a few other Fanatics were sitting. Sock was given a code violation for unsportsmanlike conduct and a $2,500 fine.
