My biggest pet peeve about the TSA is how they get all annoyed if you don’t know what randomly selected procedures they’ll be using today.

The TSA deliberately randomizes its security procedures. Different airports use different procedures, and the same airport uses different procedures at random. Sometimes you need to take your laptop out of your bag; sometimes you don’t. Sometimes you need to take off your shoes; sometimes you don’t. Sometimes you can just use the metal detector, sometimes they want you to use the rape scanner.

Which is fine I suppose; it makes sense to leave potential threats guessing. But the real problem is the attitude of the TSA agents themselves. It’s not just that they randomly select procedures; it’s that they get angry about it. Start taking off your shoes out of habit at a TSA line that today doesn’t require it? A community college dropout will soon be by, screaming at you for daring to take your shoes off in line. Start taking your laptop out when they’ve decided that today is a day for leaving it in? Some guy that couldn’t even meet the low bar of becoming a regular police officer will be in your face about it within seconds.
