That said, I still check.

I've learned my lesson....this is the first time I've heard of needing to check the torque after putting wheels back on, but it makes sense, and is now something I'll be sure to do after every time they're off. I'd guess most shops just go way over factory torque specs with their air wrenches, and as a result, it's rare to see loose lug nuts.
Semi-relevant story my Dad has told me: He was driving on the highway one day, and saw a lady with a seriously flat tire. He tried to wave her down and get her to pull over, but to no avail. A short while later, it blew, and she pulled off. He stopped to help change the tire. What did he find? One lug nut on the flat tire
Solution? He put the spare tire on, and used one lug nut from the 3 good wheels to keep the spare on.
