Not exactly op’s scenario but I had a client once who was a landlord. I was delivering some papers for him to sign off on some stuff, and he had me come into his kitchen to go over them. On his dining room table was piles of cash, like a foot tall, at least 200 stacks. Had to be hundreds of thousands of dollars. He casually walks past the table and throws a sheet over the money like “nothing to see here.” Years later I read he got busted with several hundred pounds of drugs and illegal guns, so guy was into some pretty bad shit.
