Yup. If she likes you she'll give you her number. it's pretty much that simple, unless she's a headcase. i'd say 9/10 girls give their real number to guys they're really serious about going out with.
she's not going to make you do anything ridiculous for it if that's the case... she's not waiting for you to show her your five thousand square foot condo or your background check and proof of monthly earnings. it's not a job interview is another human individual.

sure, the whole "hey take my phone and type your number in" is not the first thing you say, but it's the first thing you do that shows them you actually plan on interacting with her on a more than casual "oh hey it's you on the bus again" basis. it very easily shows that you a) are interested in her in some capacity and b) are someone who thinks ahead.
all the more reason to NOT see her in the morning. If you're a bumbling can-barely-accomplish-pouring-milk-in-your-cereal-bowl type of morning person like I am, you do not want to fall asleep while she's typing her number into your phone.

also, you don't want to revert to the "say something witty and try to make jokes and compliment her so she'll laugh and smile at me before i ask her out to this specific movie and dinner place that is either a yes or no answer" because your'e too tired. you can revert to that because you're nervous, fine, that's only human... but play to your strengths! if mornings aren't your time to shine, why go out of your way to meet her then?

plus there's nothing that will set off her 'creeper' alarms more than you showing up on EVERY bus she rides.
perfect. get her number first, ask her what she's doing, ask her what she's doing after her plans, and see if she wants to get together sometime before her plans or after. that way she can choose what she wants to do.

or you could just tell her to put her shoe on her head, that probably works just as well.
