Bad Dating Etiquette

[Cunning Linguist]

She answered her cell phone during our first date. Twice. And talked to her friend (female, at least) for 2-3 minutes each time. Otherwise, the date went famously. This is a girl I worked with who has been interested in hooking up with me (i reciprocate her interest).

Major lack of courtesy, is it possible she's just oblivious?
Otherwise it's obviously a clear representation of how she thinks the date is going.

What would you do in this situation, cut bait?
What do you do as you are preparing for the 2nd date?
Tell her straight up to get some manners?
