I used to travel for work. 100ish flight segments a year all over the country, typically carrying two laptops - corporate and client.

In one airport, I had a TSA agent yell at me that I'm not allowed to bring two laptops through precheck in my bag. That they had to go through separately. I complied but asked if that was this airport's policy because no other airport seemed to care. She swore up and down that this was national TSA policy and I should know better if I flew so much.

When I look at the TSA's success rates in audits, I tend to agree with the claim that it is more a government jobs program than a security agency.
