OK. I ordered Mexican food delivery today and the delivery lady turned out to HOT.

Funny thing is, she could not find my place and called me twice from her cellphone for directions. Should I text her? I have her number on my phone from when she called?

Would this come off as creepy? I was maybe thinking about: "Hey since my phone saved your number after you called for directions (twice), I was wondering if I could just by-pass all the red-tape and put you on speed dial for my orders???".

Then just follow up with responses by gauging her interest and replies???

If you had a conversation with her and increased her interest in you when she finally delivered the food I'd say go for it. However, if your interaction was simply she handed you food and you handed her money and said bye, I think it's odd to just start messaging her out of the blue.

It doesn't help your situation but that's why when you meet a hot girl you act as if it's on, so that you don't have to be sitting around later wondering if she was interested.
