We have a new team lead. He smokes several times a day. We have seperate smoking areas. He goes there and smokes. So far so good but unlike the other people who smoke, he gives a very bad smell. I get a headache as soon as I smell that smoke. I inquired with other people who smoke (one of them seats next to me), he told me its because they chew a chewing gum or eat chocolate or have mints. But apparently this new Team Lead doesn't do this. Should I tell him about this? If yes, how?
