Problem: Before a school football game, teacher Mr. Arliss exchanges greetings with a group of parents in the parking lot. One of the parents offers Mr. Arliss a beer. Mr. Arliss accepts because he is attending the game as a spectator and is not one of the assigned chaperones that evening. Is Mr. Arliss correct in his decision to accept the beer? Yes, because he is not scheduled to work as a chaperone. No, because teachers should always avoid consuming alcohol at school-related functions. Maybe, depending on whether the parking lot is on school property.
