I get a lot of these, our class time is 3 hours long. It is culinary so students want to cook and not sit for lecture so they show up late, and try to leave early. They want to cook, but not clean up. That stuff doesn't fly.
Our attendance policy is to rigid about tardies, and if they leave before dismissal for ANY reason, they are counted absent. If you dodge clean-up, you aren't allowed to cook the next day. You spend it cleaning instead.
It works pretty well, but we still have those who buck the system.
