It was just a Starbucks, was a girl behind the counter.
But no, lol I never told them she wasn't actually trans, lol.
My bad

My friends think I have a trans radar built in because I'm a trans woman.
But no, I have no such radar at all.
I have never been back to that place since and have only had it happen once, thank goodness.
I did tell my friends however that most trans people are nice like me and really are no different than other people. The difference is we have a brain-body mismatch and let them know they very likely would have no clue if they met one in public or not.
They still have a very good, positive outlook on transgender people
