It might be simpler to find out the identities of the specific Navy SEALS who participated in the Bin Laden mission that it would be to figure out when the Queens College Kupferberg Center Box Office is actually open.
I assume that the choral concert scheduled for Saturday, May 14 took place, despite the top secret ticket purchasing availability. After literally a couple of hours' inconvenience in multiple futile attempts to get tickets I gave up, resigned that it was "not meant to be."
If you phone the Kupferberg Center, there is a recorded announcement that does not mention box office hours of operation and it takes no messages. I visited them in the middle of the day during the week prior to the Beethoven concert and they were closed.
Nowhere on the building is it posted when they are open for business. I went to their website and saw that the box office is open Fridays until 6:00 p.m. On May 13, the day before the concert I wanted to attend, I found a parking space a quarter-mile away after rearranging my schedule to enable me to go there, and at 5:10 p.m. the box office was already closed and padlocked with no sign of life.
Still I waited, rang a bell (unanswered), but it was hopeless, so I left.
No doubt the actual performance was more professional than the Kupferberg operations strategy. But really the box office ought to get its act together or else it will potentially lose many patrons.
