A, I could not tell because of you behavior, or other factors.

B. I could not smell it.

But if I in any way could tell, I would walk. I have done so in the past. If I think a woman civie or pro, is in anyway has her judgement impaired by any substance, I will not touch her sexually. This includes my wife. It may not be rape, but it is far to close for me. Now if the amount consumed was not enough to have a major affect on her judgement, we are good to go as that is something different. But that will not help a guy get laid as she will still say no if that is what she would do normally.
