My friend had one yesterday, which could have been scary, but she's no dummy! she said some guy came up to her, asking if he could use her phone, as he may have missed his ride. without missing a beat she told him, sorry, I don't have one, but I bet if you go into one of the nearby stores, they'd let you use theirs. He said no, he was afraid if he did, his ride might leave him! she then told him she wasn't born yeterday and got in her car!
I told her he was probably hoping she had a nice, expensive phone, and when she handed it over for him to use, he'd take off with it. She then said, well, he'd be pretty disappointed as her phone is not a smartphone, old, and dog chewed!
