Problem: You are working as a utility worker on a hotel.  One of the regular customers is a financing company that usually conducts seminars/trainings on the hotel's conference room.  After the break time, you noticed that one of the speaker/facilitator went to the corner of the training hall and lit a cigarette.  You knew that smoking is prohibited inside the hotel's premises.  What will you do?  Will you let the speaker proceed with the deed?
