As far as I can see it is not your problem it is his, if he considers it a problem then it is up to him to change his behavior not for you to dictate.
As I said before get a Nose Gay.
No, when I (while recovering from knee surgery) have to back track from my place at the check out counter because the smell is so offensive, it becomes my problem.

Read about King James I. Personally, I don’t care. My concern was for this man’s lot in life. Although he was in work clothes, he didn’t look poor. He just smelled really bad. There are people on this board who cannot discuss anything rationally. They are overly sensitive. Are they all smokers?
