You're the first person in two days to offer ANY alternative beyond "Get rid of TSA because they suck!" and your suggestion is, like I said, basically the same as now, except they're forced to smile and kiss our asses. That should be gruesome.
I was hoping someone would have suggested some sort of ticket system, where you check in, and you get a number, and groups of people get called for screening. It may require a short wait, but it won't be an hour+ like it can often be on a good day. Instead, people can sit, nap, walk around, eat, etc. It wouldn't change anything about the screening process itself, but it would greatly reduce the wait, which is one of the worst problems associated with security screening.
My DMV implemented a system like that, and now going to the DMV is breeze. I've never been in there longer than 30 minutes. We could do something like that at Airport Security. We wouldn't even have to do it at the airports all the time, just at times when things get crazy, like holiday weeks, or like, y'know, now.
But no, it's all been "TSA isn't nice enough to me, well not me, it's never happened to me, but I hear other people say it, and I read one time that someone smuggled a nail file on board, and I'd rather fly with no screening because everybody in the world is nicer than TSA, because they suck!"
