With the exception of reliable movie showtimes, live performances rarely start at the exact indicated time.

But a few minutes of delays are easily forgivable, especially for touring concerts due to the complex nature of setting up in every city.

But two hours past showtime is not cool, no matter who the headlining artist is.

Madonna is known for her perpetual tardiness. But when the iconic queen of pop recently changed her Miami concert from 8:30 p.m to 10:30 p.m., she pushed fans over the borderline.

Fans have long grumbled over Madge's disregard for punctuality, but now one fan has had enough.

Nate Hollander, who paid $1,024.95 for three tickets for the Madame X tour for the December 17 performance at the Miami Beach Fillmore, filed a class action suit in Miami-Dade County court.

The show was rescheduled for 2 and 1/2 hours later, which was too late for Hollander to attend. He also said the tickets' resale value tanked because of the later showtime.

Concert promoter Live Nation changed the tour's opening performance time and for subsequent shows, due to Madonna's consistently late appearances.

Because of Miami-Dade County's curfew laws, those who are under 18 years of age cannot be out in public without an adult past 11 p.m.

Now, unaccompanied teenagers who have been planning on seeing Madonna months in advance will be missing their chance.

Live Nation and Madonna have not offered refunds.

The singer's November 7 Las Vegas engagement was originally scheduled for 8:30 p.m. but actually did not start until 12:07 a.m.

Her nonplussed attitude was evident when she told her audience:

"There's something that you all need to understand, and that is, that a queen is never late."

Umm, but she was late.

While the audience cheered in exuberance over their highness, Twitter reactions to the posted video knocked her off her throne.

Ardent fans are finding her Madgesty hard to love.

Does she care about her fans being inconvenienced?

Those who are done with her are letting her know "The Power of Good-Bye."
