I'm in school and have only 30 minutes for lunch. I don't have time for anything other than buying food and eating it.
Bring sandwich to school.
Eat sandwich in 5 minutes.
Yay 25 minutes of reading!
I myself eat something (I either eat a sandwich and drink some cold soda (yeah sure a few minutes lost on going to as store) or I go and buy myself a hamburger with fries and soda if I'm in the mood for it), read some good book, sometimes play "Magic: The Gathering" with a friend, chat with a friend, browse the Bethesda forums and other random websites and sometimes if I'm really tired I take a short nap.
:D Love breaks.
