I would have never thought of being so direct and it seems interesting but I do have some ethical issues. There's a difference between being direct and being rude.
It might be ok to forget about the routine as you say but i do have problems with being disrespectful with a woman and even more with a good friend.

And about the alcohol, i wouldnt be capable of getting a girl wasted just to fuck her. I cant do that cause i wouldn't accept it and it is something close to rape.
A glass with vodka wont harm anybody. It's just to have a little bit more fun.
