rflook,
I have read your previous posts, and the way I see it, you are progressing. But aim for perfection.
First of all, for No.1, you had a great routine in opening up the target and sarging her through the time, but one thing I have seen in your previous posts is that you never number closed. So, since she stated
"it was lovely to meet you rob", instead of saying
"lovely to chat to you but have to shoot", say something like
"As much as I'd love to stay and chat, but I really have to go. I'd like to get to know you more better, lets exchange phone numbers

" - goof guys theory.. I know.. BOOHOOO
or
"I can't stay long, but you look like someone I wanna know, Period!! (take out your phone) Fill in your number.."
or
"I have to go.. Your cool / you guys are cool. I like long walks on the beach.. (take out your phone)Join me" - My cup of tea, works everytime
Or make up something that leads to numbers. Never ask her number, just end your speech in full stop, make a statement and she won't say no, trust me

..
It's the same for number 2, but bear in mind you should know your time limit. I hope you find my piece useful, but keep updating. Practice makes perfect, and remember to have fun. All the best, cheers..
