Yes. One school I went to let students leave for lunch as there wasn't staff at the school who made the lunches. You either packed or went somewhere.

Anyway, I would leave for lunch and not come back after because I hated afternoons. They ended up suspending me for that.
Also, although not the same, I got three days of in-school suspension for not providing an excuse for an absence of mine. I could have lied and forged an excuse, but I wanted to be honest. I didn't go that day because I was too tired.
Oh, I also got expelled for a year, but that's for a different thread.
