The Matthew Perry thing is cringe, but at the same time they matched. If she wasn't interested due to age, she could have ignored him. She also states that he was a nice guy and from the sounds of it he wasn't being overly forceful and intimidating. I could understand the power balance argument if he were seen to be manipulative or using his status to pressure her, but seemed like they were just chatting. Him acknowledging he's her dad's age kind of suggests that he is aware it might be ridiculous. I'd be more wary if he downplayed it and tried to move her her attention away from it.
What gets me is that she acknowledged he was a nice guy and says she feels a bit guilty about it...but she still did it anyway. He is actually quite vulnerable, and just because she is younger doesn't mean that she is more vulnerable and not as predatory. Someone from high-school used to target older, larger "uglier" men as they'd be so grateful they'd spend loads of money on her.
