Last night, tens of thousands of people packed the Citi Field stadium to see Beyoncé bring her Formation tour to New York. The evening was full of spectacular choreography, vocals, and one very viral sneeze, but for two New Yorkers who spent $85 apiece on tickets, it ended after just half an hour: Allison, a 26-year-old Brooklynite, was made to leave the stadium, along with her girlfriend, for using the men's restroom when the line for the women's room was too long.

The couple had been at Citi Field along with a few friends for several hours before Beyoncé took the stage at about 10 p.m. During that time, Allison said, many women were using the men's room, as the line for the women's room was excruciatingly long. At one point, she said, there were about 50 people on line for the women's room but no one on line for the men's, and when she used the men's room earlier in the night, she was one of a dozen other women doing so. At another point, she said, they overheard a man telling his girlfriend to use the men's room, because of how long the line for the women's room was.

About 30 minutes into the show, after Beyoncé had performed "Formation," "Sorry," "Flawless," "Run the World," "Mine," "Baby Boy," "Hold Up," "Countdown," "Me Myself and I," "Runnin' (Lose It All)," and "All Night," Allison and two friends noticed Citi Field security trying to force her girlfriend to leave the stadium for using the men's room.

"We pressed security with questions about whether or not this was actually a policy, and if it was grounds for being thrown out," Allison told us. "When I continued to ask these questions, and said that many women, including myself, had been using the men's restroom throughout the night, the security officers told me I was now also being thrown out and police would be called."

The guard who'd been yelling at her girlfriend to leave refused to say why he was throwing her out other than saying that using the wrong bathroom is illegal, Allison recalled. More security guards showed up, including one female guard, to whom Allison and her friends turned for solidarity, but to no avail.

When the guards threatened to call the police, Allison told them to go ahead, as she didn't believe she was violating any policy. When a police officer came, she says she demanded to know exactly why she was being asked to leave, at which point she says the officer handcuffed her and took her to a holding area. After some time, she was released and not arrested, but was escorted to the gate and made to leave, along with her girlfriend. (The NYPD didn't have any record of the incident.)

Gothamist has learned that Citi Field allows people to use the bathroom consistent with their gender identity, in accordance with the NYC's laws prohibiting discrimination on the basis of gender identity or expression, but the venue does not appear to have a written policy prohibiting someone from using the facility that corresponds with the opposite gender with which they identify. Citi Field declined to make a statement on the incident, or its policy (or lack thereof).

The city's protections specifically aim to provide bathroom access to people consistent with their gender identity, but don't extend to cisgender women hoping to use the men's room, or vice versa. Bobby Hodgson, an attorney with the New York Civil Liberties Union, said that to his knowledge, there aren't any criminal penalties associated with accessing a space that does not conform to your gender identity, but private venues such as Citi Field are entitled to create separate spaces and enforce them.

"It feels like a literal policing on what women do with their bodies," Allison said. "I think that the architecture of many public spaces is inherently somewhat oppressive towards the needs of women. Huge lines for the women's bathroom are not uncommon at all—if there's no line for the men's restroom at any point in the night, yet the women's line is at least 50 people deep the whole time, then clearly there's a problem that is not being addressed. Presumably, the crowd last night was a majority of women. Maybe that's not common at Citi Field, but perhaps they should've made proper accommodations. Or at the very least shouldn't have punished female visitors for what is essentially a design flaw."

Allison said she'd love a refund on the tickets, as she missed most of the show, and plans to file a complaint with Citi Field and possibly the NYPD. If Citi Field does have an explicit policy prohibiting the use of single-sex facilities that don't correspond with one's own gender identity, which the venue could not confirm today, Allison said that certainly wasn't made clear last night, and no one she talked to could state an official policy.

"Really, I just can't believe we all missed Beyoncé because some guy cared where we peed," she said.
