Why didn't she report it to the police?
I'd just be guessing, I dont know what was going through her mind at the time. Knowing her, she was happy to have gotten the hell out of there and wanted to finish out her shift without spending time making a police report.
And, (again, I dont know that she took this into consideration or not) even if she had made a report, in all likelyhood the cops would have gone and talked to the guys at the house, and of course they would have a very different story, and then we get the wonderful he-said-she-said situation that might not go anywhere.
Plus the idea of testifying if it actually became a thing...
Plus the fact that she was probably more than happy to never see those clowns again...
I dunno. Maybe all of those things, maybe none. I cant honestly say that I'd call the cops just because a drunk tried to pick a fight with me, especially if nothing happened. I'm guessing she had a similar mentality after this incident. A few drunk guys made lewd comments, eyed her like a piece of meat, tried to take her by the wrist or something and kept insisting that she 'hang out' with them while also telling her how 'hot' she was.
After she shoved her way out of there I dont think she had much incentive to make a report. It was probably scary, and creepy, and once it was done I dont think she wanted to revisit it or make a thing out of it.
Just my guess
I do think it was ****** she had to pay for the pizza. The manager should have at least called the cops for that, and covered the pie by some other means.
