bad breath
imahlah asked:

I have this co-worker that smells bad and we do not know how to approach her. So we say nothing. We drops hints, like people need to take showers b/c the chair is starting to smell, but we still have this problem. I use fabric freshner for the chair, but nothing seems to help. We asked her best friend to speak to her and she said that she has been saying something too her, but it does’nt help. What should we do?
