The parts you missed? Hmmm, how about the part where it would have been rather obvious to him that his advances were unwanted right around the part he tried to kiss her with tongue if not earlier. What about the part where it's rather difficult to get off a bar when you're drunk and there's a guy leaning over you. Then there's the part where women are under social pressure not to kick up a big fuss about this kind of thing at the time because gee "it was only a bit of fun" and they're "overreacting".
If she had some pushed him away and got off the bar, I can pretty much guarantee you we'd be seeing comments just like yours about how she was freaking out over nothing.
Let's also not forget about abuse of power. That was her boss, two levels up in the hierarchy of the company. She was shocked, and I'm sure most people can understand how awkward it is for her to have had to demand her boss stop groping her.
Can someone tell me how you put your hand down to grab someone's butt while they are laying on their back on a bar? That seems kind of difficult. I just tried it and it took me rolling someone on their side then doing it and then rolling them back to put my hand down their pants. I am just recounting the information presented to fairly run through this situation. We need to be fair to both parties if were are going to be passing judgement on people we don't know and were not at this event. We are only hearing one side of the story so that means we need to scrutinize it even more.
