Bad breath.....how will you tell that someone that he/she has bad breath?

We have a guy at work with CHRONIC bad breath and a few people have told him & I personally felt horrible about it too. I didnt have the heart to say anything BUUT I have offered gum or mints. I usually play it off by offering it to everyone and him last like he wasnt the reason I brought it out. :) its not easy to deal with.

I know someone like this in our family , everyone talks about it but no one has the guts to tell the person that her breath smells really bad as no one knows a polite way of saying it where it won't hurt her feelings , especially since some of us think it might be the medication she is taking .
