What is that, you ask? Could it possibly be?!
Yes, yes it could. It's my poor receiver on the subway tracks.
I was dumbstruck. How could this happen?! What do you do?! The latter flabbergastatement was exactly what I said to the girl standing next to me, who replied "Um, not go down there? I'd go ask someone upstairs." So I did.
The nice booth attendant said help would be coming (after a lengthy explanation of what the hell it was that I actually lost) and I should wait on the platform next to the item. So I did. And I stood there for an hour, keeping spitters and rats away from my poor, lost Dexcom. At long last, two dudes with pinchers on a pole came to my rescue and plucked Dex from the depths of filth. I carefully - with Kleenex-protected hands - dropped it into a plastic bag I had with me, and finally headed home to give Dex a much-needed "bath" with rubbing alcohol.
