[TOMT][TV SHOW] Transgender woman faces discrimination at the office

What I remember: a woman is complaining to her boss at the office about how she's uncomfortable with one of her coworkers using the woman's restroom. If I remember correctly, she doesn't actually fully say "because he's a man" or anything like that, instead kind of dancing around the issue but it's clear she's angry. Then, the transwoman character shows up and is fairly politely but reluctantly asked by the boss to stop using the woman's restroom. I don't remember how it all concludes.

This may have been a tv show, movie, or possibly a PSA about discrimination or something. Leaning TV show right now though. Likely from the 2000's. Thanks for the help.
