I want to say y'all are paranoid. But.
My wife came home one night, hammered. OK. Fuck me, she drove home?! Not proud to say, but we drank and drove a lot in those days, got a hotel or cab if we were smashed.
Next day she doesn't remember a thing but having a second drink at the bar with the girls. Nothing else. C'mon! Could hardly believe it, chewed her out for driving drunk, she insisted she only had 2 or 3 drinks. Bullshit. Takes more than a couple of drinks for us to black out. Hell, we never got that drunk.
She got to talking to her friends that were regulars at that bar. Regulars who had the same bar tender. Same exact experiences. You add it up.
She wouldn't report it. Because what are you going to report exactly?
Having said all this, that's my only story on the subject. And I've done a lot of sketchy shit, ran with sketchy people. Date rape drugs are not as common as you might think. But they are indeed a thing.
