I do too. I work so close to home, so I can go home to take care of the pets and make lunch. My lunches are usually right at an hour, but I'm not racing the clock to get back.
I'm salaried, but I have a 2.5 hour break in the middle of the day. Sometimes I have technology stuff to take care of for my campus, but most of the time I sit around and do nothing (ie surf the net, play WoW, go home for lunch, nap etc.).
I've got a pretty open work place as well. Throughout the years, my philosophy has become that my lunch hour begins when I get to where I'm going. Drive time does not count. I typically go home (about a 15 minute drive if I don't pick up food on the way). So, I'm usually gone a good 1 1/2 hours.
