So, dmopz - they didn't take your car? And let you go? That's alot more lenient than a few years ago, when it was all about raising the money for those cameras.
It takes a long fucking time to be processed into that hell hole. When your friend finally gets to the wall of phones, he'll be in for a big letdown. Most jail-house phones are a cruel joke - Cook County's are total bullshit. The one's that work are only for collect calls. And EVERYONE he (and all of us) knows has, at some point, selected an option that refuses to let collect calls from jail through- who expects that some day a desperate, dope sick friend is going to REALLY want you to pick up? The staff just laughs at you, while there are REAL AT&T pay-phones on the wall behind them. I know it's hard to believe, but it's really true. Real pay-phones outside of the holding cell while your friend desperately tries to use a toy phone. Cruel and unusual?
Anyway, if he I-bonds out, he won't need money. He can call for a ride once he's outside. When this shit happened to me, there were about a dozen guys who managed to hide their cell phones, and were cashing in until their battery died - I don't know if people can still do that.
It's pure hell, but most people get out after a really long day with Satan's minions. I know I painted a shitty picture, but he'll be ok.
