There's a pretty big difference between holding a door for someone or buying them a drink and paying for their movie, popcorn, dinner, and gifts all when you literally just met them and then again one day later.
I didn't say he was a creep. I said he's throwing too much money at her for this situation. That implies there's something off, which could be a number of reasons. That's why I asked how old he was. If he's a young guy then he could just be inexperienced and not have a great idea of how to express his interest other than bombarding her with attention and gifts. I think most dudes have been there more or less, but it can sometimes lead to some shitty outcomes with some guys, especially immature ones that haven't got a lot of experience dealing with these emotions, if the subject of this attention doesn't meet their expectations. It's why I suggested having a conversation with him about what those expectations are and where she is at in her own feelings towards him to clear the air before he gets too invested. If he's an older guy than it becomes more suspicious as they should know better than to buy affection with gifts.
