I give lunch detentions if the student can't stay after, but if they take a lunch detention they have to serve 2 to get their 30 minutes in. I'm so mean!! Trust me hon...teachers hate detentions as much as the students. I teach with people who won't give them because THEY don't want to be punished! lol I'm with KayAnn....grin and bear it and get to class on time from now on and the problem is solved. Trust me...in a battle between a teacher and a student, the teacher wins 98% of the time....fair or not.
