I won the TSA Pre-Check lottery this morning, it's a 1 in 3 random chance of using it on any given attempt. Pre-Check was empty (the main process was packed) and the whole security process took less than a minute. Laptop stayed in my bag, shoes stayed on, no naked pictures taken. The TSA agents are still snarky, but you don't have to put up with them too long. The process improved my customer experience, but the people are doing their best to keep you miserable (see Helsinki for a good customer experience program). TSA Guy: "Popular program, had 144 people use it in 8 hours yesterday."
