Today, I refused to let two students into class because they were 15 minutes late. It turns out they were late because they had gone to buy me a birthday cake. FML
I am the original poster. It was an adult ESOL class. School policy - strictly adhered to - is that students can't be admitted if they are more than 5 minutes late and all students know this. Lateness is disruptive and disrespectful to other students. We all eventually had the cake later anyway!
