quandaries

This is not for the ladies. Ladies don't use the turlets as far as I am concerned.
This is strictly for the fellas.

Okay, this is a series of semantics questions.

1-Rest room is vacant, where do you #1.

2-Restroom has occupant in location C, where do you #1
Bonus: where do you #2.

3-Where do you wash your hands.

4-You are doing #1 in location F.
A stranger enters the restroom and begins talking to you directly, and then proceeds to also do #1 in location E. What do you do.
