In Felicity's case, she brings a ton of snacks with her, so it's unlikely that she'd accept.  On the subject of how to bed her, I did mention that non-con was fine as long as the other person's okay with it.  If not, I'm pretty sure someone could take advantage of her gamer side, make a bet with her (even if it's more of a veiled meaning), and when they win, it'd be bedtime.  (I feel like I'm being difficult here... :/ )
