You aren't separated from your items.
Eh....yeah, sometimes you can be.
Memorable trip through MCO (probably) last January. DH got Pre so our under-12 son went with him. I went through the normal line. I don't go through the naked machines, so I get patted down.
I had stood in line, listening to a wannabe standup comedian (along the angry lines of Lewis Black) TSA agent scream at everyone that we're in public, it's a public place, there are people around, that we should not just let our bags go through the scanner until the scanner person was ready for it. On and on and on.
And of course his colleagues were NOT doing the line that way. Put the bag through, do NOT wait for it to be your turn.
Anyway, I get up there, with the bag 100% out of my sight, and say that I don't go through the scanner, and the JERK of an agent left me standing there, on the other side of the scanners as my bag was, for nearly 10 minutes. I stood, smiling, wondering where my bag was (and shoes and 311 bag etc), while trying to get his attention, catch his eye, let him know that my bag was totally separated from me at this point, and he wouldn't let me catch his eye. He didn't call for a female agent, either. It was awesome. He was the best. (ha ha ha) Finally, around 7 minutes from the start of this, he called out for a female agent for me. She was there immediately. I said that I had been separated from my stuff for a seriously long amount of time (in security-land), and she could not have cared less.
So let's see...I'm a good guy, but pretend I'm a bad guy. I've let my bag go through to an area I'm not in, and it's been over there, on its own, for that long. Nice, eh?
So I was reunited, patted down, and moved along my way.
It's not the only time I've been 100% out of sight from my stuff, either. But that was the most obnoxious time.
Since the OP has medical stuff that causes her to be patted down, it's entirely possible she could be separated, too.
So bury the wallet deep in the bag. Hope you're taller than I am so you can try to keep on eye on things.
