Travel Advisory?

You may have brought this up before months ago.
How do you know you were not harmed if it was Rohypnol, which
erases memory. And if you were not harmed, what was the point in drugging you?
Just for kicks?

Perhaps I did bring this up previously.
The point in drugging me was for them to get whatever they could from me.
As I attempted to indicate I was extremely fortunate that nothing of grave consequence happened.
How do I know I was not harmed?
Because some of it was caught on video and it is possible to recreate some of it.
The other part is that I am a sentient being and I am able to recognize to some extent how I am.
