What's the funniest/creepiest/most interesting place you've seen an airtag ping up?

My dad uses airtags (or some similar device) to track shipments, normally we remove the airtag once the customer confirms receipt and they can do whatever they want with it, but buisness being buisness a couple slipped through the gaps, i was removing some for him, some of which hadn't pinged up in days or months.

I saw one that i remember setting up for him that last pinged up at a strange looking building like two months ago now, looked like a power plant, out of interest i googled the name before removing it and found out it's an incinerator, looks like they must have discarded it with the rest of the packaging and it ended up at a waste to energy facility (basically a giant boiler that burns waste to make steam for a turbine) that airtag is carbon now.

And i found another that appeared to be in landfill.

What's the most interesting ping you've received?

PS: We're going to start advising people not to throw them away in a bid to reduce e-waste
