Another bathroom tale:
Was in a casino on the toilet, and my gf came in and shouted "Beth??" (she hadn't seen me come in, and was looking for me). Of course I'd not yet learned a femme voice, so I just kept quiet. After another yell, she left.
I finished, walked out and saw the communal sink where one washes their hands...and there were 3 older ladies there! I made eye contact, got flustered--if I washed, awkward questions may be asked, if I didn't, I could leave faster and ignore them...I took the path of least resistance and quickly exited.

In hindsight I can laugh at myself, panicking like a little girl! My apologies to the community for giving us a reputation for not washing our hands!
