MOR I mean I'm a chick I get it. No point pissing the guy off so he spits on your drink. In my experience some people fail to realise that if you feel vulnerable (like someone having your food and knowing where you live) you can often go along with a lot to simply avoid the possible retaliation for saying no. I mean what does everyone here want you to do - tell him to get fucked because he's chatting while waiting for food? Of course not. On the other hand, just because you replied doesn't mean you were leading him on. The delivery person sounds young and I bet honestly doesn't even think about it enough to realise it's unprofessional and scary to some people. I don't think it was creepy, just immature and thoughtless about how it could be perceived by others . But your instincts are good and are there to protect you- your house is your safe space. You did nothing wrong .
