On the 13th anniversary of one of the worst attacks on American soil ever committed, Northern Virginia-based yoga studio Bikram Arlington tweeted some really awkward comments about 9/11, including an unfortunately worded anniversary discount. Oof.

The yoga studio has since deleted the tweets and apologized. Profusely. Still, let this be a lesson for businesses: think before you tweet, even if you have “yoga brain.”

I wrote that stupid post at 1am with yoga brain. I’m sure some of you know what I mean. Z fought against it don’t blame her!!

To make matters worse, the owners of Bikram Arlington, Zahra Vaezi and Frank Machnick, told the Post that, while they’re sorry for the tweets, they think people are blowing it out of proportion, “like that man who punched his wife,” Vaezi said, referring to Ray Rice:

“It’s like that man who punched his wife,” she said, referring to ex-Ravens player Rice. “I mean, that’s upsetting. But I think it kind of gets blown out of proportion.”
