Kept it simple this week. Just left a fiver on the coffee counter at the convenience store on my way to work.
I rather fancy myself a super spy, slipping it onto the counter in one fluid movement as I make my way around the island to the cooler to grab a Diet Coke. Of course, they have cameras rolling, but I doubt anyone would go back and look to see who left it.
Just as I was leaving, two men came in, so it's possible one of them found it, but I was running late to work, so once again I didn't get to see the moment of discovery.
