If someone sued because their family member had a heart attack in a tent, how many people are honestly going to say, "Shame on Best Buy for not taking care of that guy?"
Nobody in their right mind would hold BB responsible in that scenario. Yeah it sucks that a guy died, but it was gonna happen no matter where he was. That's just bad fortune. How can anyone hold you responsible for that?
Maybe I'm just too logical, though. It's all the irrational people that ruin it for the rest of us with stupid stuff like lawsuit abuse.
