Double or nothing...
At risk of making myself look like a bumbling idiot, I have to report this:
It happened again.
I was entering Airport station, and pulled out my wallet to get my stored-value ticket before I appproached the stiles. Just as I stepped up to an empty style, a stranger (yes, a young, foreign-looking male) stepped out from the next stile over, and reached out his arm quickly to block me from going through. I looked up in bafflement, a little irritated at being delayed. He said nothing, but pointed to me to turn around.
"Who is this guy," I wondered, "to tell me I can't take the subway? Everybody else is taking the subway. My ticket is perfectly valid and has plenty of money still on it." I turned to see what he was pointing to.
You guessed it. It was the $10 bill that had fallen out of my wallet and lay on the floor about fifteen feet behind me.
I really need to start actually putting my money IN my wallet, instead of just wadding it into my back wallet pocket.
