Years ago while living in Reno, I drove the truck used to vacuum out the pota-poti's. Same weekly route with different route each day. It payed VERY well and over the couple years I worked there I found all types of jewelry and on a couple occasions found fat wallets.
It seemed impossible they could have dropped them and not realize it, but I guess when you look down and see your wallet nestled in what looked like green and/or yellow pudding [man, some of those guys needed medical help] It made it harder to reach in, I guess. [I did tell the forman's but no takers] I still have an 1897 silver dollar I found at the bottom of the tank, in my collection. -Haha
I remember our work shirts read.. 'YOUR SHlT IS OUR BREAD AND BUTTER."
