If I knew the source or saw it falling off the truck I wouldn't touch it. If however there's just sudden money laying on the highway I'd get out and go into a theatrical over the top praising skyward yelling 'now I can afford the surgery' or something. Assume you're being filmed. And ffs grab off the grass under the guard rail as it's not blowing around and it's bunched up , pocket it. Take minimal..don't linger scooping up singles for the camera. Approach the person filming empty handed asking is this divine intervention and what is going on with this face . If you pull up in a bucket and the first thing you think of is paying off bills, keep it.
