If you haven't given up on the human race yet....

Quick-thinking S.F. pair nail man slipping his companion a mickey: It looked for all the world as if the couple on a date -- he was darkly handsome and a little older than the pretty, petite blonde with the Russian accent -- were having a great time together.

"A really great time," their waitress, Karri Cormican, recalled thinking. "She was facing him, had one of her legs up on the bench seat." Good body language.

So it came as a shock when after the woman left the window-side table to visit the restroom, Cormican saw the man shake a white powder into the Hefeweizen beer he had ordered for his date....

And then, it gets worse:

Tatiana was stunned -- she said it was their first date, and they had met at a salsa dancing class only weeks before. Earlier, he had picked her up in his BMW after her classes at City College. "She's a trusting young lady," says David Merin, the assistant district attorney who prosecuted the case.

Cormican had to repeat herself several times before Tatiana absorbed what had happened. And then things got even worse.

The bartender rushed outside to tell the two women that while they had been talking, Szlamnik had dropped two pills into the new beer Tatiana had left behind on the table.

"He did it again," she said.
