I take my risk management and street crossing technique seriously. I’m not going after any money if I’m not sure I’m not risking my life.
In medium traffic, there are practically always gaps where it’s safe to cross a freeway. I’d wait for one and then grab it, and I’d think about how long I’m waiting around for the bill, and what else better I have to be doing. So it becomes, “how long will I wait for an opening for that bill?”
I was walking the shoulder of a highway once, found a twenty right there at the edge of the grass. If it was in the road I would have no qualms about flagging cars to a stop to retrieve it. To get my attention I would need to see multiple flutters, like @zenvelo.
Ever been in one of those money wind booths? I have, three times. I can snatch some scattering bills fast.
Funny you should ask this because I sometimes pay our chauffeur his wages by tossing out cash from the sunroof, helps with his emergency braking too & so it’s all good.
