My wallet fell out as I got out of the Uber at SFO when starting the vacation, and I didn't notice until I was on the plane. It was a smaller wallet than my regular one, same dimensions as the passport, and feeling the passport in my pocket made me think I still had it. At the end of my vacation, Uber Support finally replied that the driver had my wallet as I hoped. That was right before I ordered the food that made me nauseous. I was able to pick up the wallet with everything including cash intact from the driver when I finally got back to SFO.
