How do you find a wallet on a taxi when you don't know the taxi company you take a taxi from union station in Chicago every day for school. you know exactly what is in there but theres no id. watdoudo?

Short answer: if there's no id in the wallet and you don't know the cab company or cab number, chances of recovering it are pretty much zero.

Longer answer: you could call every single taxi company listed for Chicago and see if any of the drivers turned in a wallet with no ID but fitting your description of it. If you can remember the color of the cab, at least you can rule out a few companies. If it was white, you can rule out Yellow Cab, for example. Start with the big ones first - Yellow, American, Checker, Flash, Blue Ribbon, then work your way down the rest.

Final answer: next time, always, always, ALWAYS, check the seat before you close the door of a cab. that one step will save you and the driver a LOT of trouble.
