Ha! I asked a dude at the mall if I could use his cellphone to call my mom.( Mine died.) He looked at me like >.> fuck no, but he ended up giving it to me and stared at me the whole time.
Like I really wanted his phone. -_-
Answer to question: It depends who asks for it, and for what reason.
Man: I need to call my gf.
Me: I don't have one sorry.
Kid: Hey can I use you're phone real quick I can't find my sister.
Me: Of corse you can, gives phone* and $245 dollars, here take my shoes to. .-.
I had a young girl ask to use my cell once, I let her and I stood right beside her as she used it but since then I haven't had anyone ask to use it. I don't know if I would again though.
