I left a MacBook Pro behind in the bin at a security checkpoint at Miami International Airport a few years back. I realized it when I got home, looked up the airport's lost & found number, called them, and they had it. I was shocked. They held it for my dad to pick up.
I left an iPad in a men's room at Tokyo SkyTree. Went back 20 minutes later and some random guy (regular guy, no uniform or anything) came out of the men's room and handed it to me. I guess I had that "just lost my iPad" look on my face.
I was checking in at a hotel in Amsterdam with my suitcase 2ft behind me with a duffel bag on top and my backpack inside containing my laptop.
In the 30s it took me from the point where I took my wallet out to the point I was done paying somebody had opened up my duffel bag and stolen my backpack. I just bought that MBP 2 weeks earlier and just finished the hassle of setting it up.
TBH, whoever took it deserved it, it was the smoothest thing ever. I had friends with me all standing around and nobody saw it get taken.
I’ve grabbed the wrong Air out the airport scanner. It even had a dent in a similar place. I opened it to check on it as I walked off and the saw it was wrong. The other laptop was just leaving in someone else’s hands. Close call.
