So, I go to our local Sonic Drive in Restaurant during their "Happy Hour" ($1.07 for a 44oz drink, cant beat that with an ugly stick) and I had been slightly flirting with one of the new female "car hops" for the last week or so, probably 4 or 5 years younger than me, cute brunette, ect. so, since I take monday afternoons off, I went chatted with her for a little while today, figured, Ok, seems like she's kinda into me, so I ask her for her #, and she looked excited, she really did, but then she informed me that she had recently cancelled her cell service and hadnt gotten a new one yet. then we spoke for a short time and she rolled away and proceeded to roll right into a chair behind her and almost fall over.

Lots of mixed signals here. She sounded legitimately happy to be speaking with you, but that could just be the attention from you and/or her general job requirements talking. Bear in mind that she is a waitress and she earns tips and shifts by engaging customers and being personable. I would be lying if I said that I had never used flirting in a service position to get better results or get what I wanted.
I hate to say it, but I would air on the side of "forget about it" rather than "keep going for it." While it is true that she might be embarrassed about a living/financial situation that would explain not having a phone, if she really wanted to get together with you, she wouldn't let a lack of cell phone service stop things. She could have asked for your number, or even your email or social networking info.
If you are really into this girl, I suggest dropping by again, and slipping her your number and keeping the conversation brief and casual, if even talking much at all. You don't want to make her feel like you are creeping and it is nice to put the ball in her court to find out what is really going on. If she likes you, she will make the effort to contact you.
