More bread

I doubt anyone will see this since this forum is ridiculously out of date but I came across a post by “boofer” about bread being left on his windowsill. I have a similar situation except it’s being left on my vehicle while I’m at work. Its happened 4 times and each time the amount of bread increases. Last time I had like 6 different things of bread products left in a shopping bag hanging from my cb antenna. Any thoughts are appreciated.
