How rare is it? Is it pure luck?

I moved to Zurich in 2019 and had my purse fell on the ground upon entering a tram. I realised it only after the tram door was locked and tram started moving. I alighted at the next tram station and ran back. My purse was still there only this time instead lying on the ground, it was hung / latched onto a barrier. None was taken / missing. (I had my wallet, keys & phone inside).

Yesterday, the same thing happened. Only this time my purse’s strap broke off when i was crossing the traffic light and i only realised it when i was going to pay for my grocery at Lidl.

I went back to that traffic light (10 minutes interval) and found that somebody has picked up my purse and tied it on a construction fence. Nothing was missing.

I am wondering if this is a normal thing (somebody finds a purse and takes effort to hang / ties it nicely so the owner can retrieve it back) or was i extremely lucky?
