Once the door opened ,my first word was ..
Me : Hi , are you ladyboy ?
Nook : What ??
Then she bang the door when I walk away .
OK thanks. So not being judgmental at all, but just for clarity;
You thought she looked like a ladyboy, asked her, she got the hump.
So if she is a ladyboy she is guilty of duping customers and you are in your rights to walk.
If she's not, ie a cis girl with masculine features, she is understandably upset.
I'd like to have gone through with it and satisfied my curiosity

Good for you for doing what felt right to you
