Yeah, I'm supposed to believe that the pregnant woman who just got off a long shift and is literally straddling the bike in the video somehow muscled her way through a group of large male yutes to steal their bike? Sure, that could be the case, but Occam's Razor seems like it would apply here. She got on the bike, paid, started to leave but was essentially held hostage for social media points. Again, I'm more than happy to be proven wrong here.
Her lawyer says she has receipts to prove she paid for the bike. I'd also be surprised if there isn't CCTV footage of the entire incident available somewhere.
