The taxi was not 'ordered' from taxi service. We flagged it down on the street. So no traceability back to a specific taxi company.
No receipt, just a quick cash transaction.. 14 euro fare, I gave him 15, and left. So, no good way to trace it back to a specific driver.
No name, email or phone to identify me in the bag.. perhaps a lesson going forward(?).
I don't have an Apple phone, so Airtags is not an option.
In regards to the choice of location of the shoulder bag.....yes.. 99% of the time it remains on my shoulder...yet in the process of helping my wife with her seatbelt, I unconsciously must have removed the shoulder bag. Not something I generally do....
I can replace the camera and other items...it's really just the years of photos on the SD card that I really wish to recover. I had only a small percentage of the SD card photos backed up elsewhere.
My wife told me not to replace the Rick Steves bag with a like item, claiming bad luck, as an identical one was stolen from my luggage in Italy last year... Despite her warnings, I really like that particular shoulder bag, and will likely order another.
