LGBT media outlet The Advocate picked up the story this week of a group of transgender women who were asked to never return to North Portland bar the P-Club.

According to a report on our local FOX affiliate, a group of trans ladies went to the P-Club regularly every Friday night for two years. Then, last week, the bar's owner left a surprising voicemail for one of the women, which she happily played for both media outlets and the state Bureau of Labor and Industries.

"Hello, my name is Chris. I'm the owner of the P-Club Bar and Grill," says the voicemail, according to the story. "Unfortunately, due to circumstances beyond my control, I'm going to have to ask for you, Cass and your group, not to come back on Friday nights. People think that A) we're a tranny bar, or B) that we're a gay bar. We are neither. People are not coming in because they just don't want to be here on a Friday night now."

Wow. The state is now investigating the bar as potentially discriminating against customers. But if the voicemail holds up under scrutiny, this will be a unique case because of how blatant the discrimination is. Transgender people report feeling discriminated against often, but often discrimination is hard to prosecute because it can sometimes only be seen in statistics like pay grades or housing rental tendencies. To have someone actually come out and say—in a recorded voicemail—that someone is not welcome as a customer because they're transgender, well, that's a rare case of discrimination that's going to be hard to argue against.
