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.
