Chances are she never put herself in the position where someone could spike her drink-does this make sense?
What does that mean, she never ordered a drink from a crowded bar?? Seems kind of over the top to me. Her saying's nice at face value, but I agree with the others, it doesn't really hold up - there are tons of people who are taken advantage of without their 'permission'. And likewise, there are many people taken advantage of who assume the other person has their best interests at heart, but without realising what they're getting themselves into. They rarely are actually giving permission to be taken advantage of though.
p.s. please don't slander other guests on the site - not everyone sees things the same way.
