Eli Roth says he came dangerously close to being taken advantage of by a mother and her daughter in Vegas 5 years ago — after the insidious duo ROOFIED one of his drinks … but thankfully, Quentin Tarantino came to his rescue.

The “Hostel” director recounted the story during an interview with Fox Vegas, claiming he was out for a night on the town with Quentin and RZA from Wu Tang Clan — when he struck up a conversation with a mother and her daughter at some nightclub.

As the conversation unfolded, Eli says he began to feel really woozy — and the mother/daughter tag team offered to bring Eli back to his room.

But Quentin immediately knew what was up, and stepped in — insisting on taking Eli to his room himself.

In Eli”s words, “Quentin Tarantino saved me from getting roofied in Vegas.”
