How do you

Oh man that reminds me of a time when I was waitressing and everyday there would be this family that would come in well just a couple guys that would come in and I am not exagerating they smelled like they had not taking a shower in a week or washed there clothes, I felt very bad for them but I remember I always dreaded having to go over and serve them coffee that would be all they came in for they were not homeless or nothing like that I just think they didn't really care how they appeared or smelled it was awful.

If I won't stay around them for long, i will keep quite. actually, i don't like to hurt their pride

I can't say that, i don't want that they feel embarras or get hurt. I do rather keep quite and move somewhere away from him so that i will not smell him. So maybe that way s/he realize that he smell terrble bad.

hi,well i dont think would say that a person smells. Its really rude to do that i feel. for all you know it might just be his natural body smell. well also by telling him that it would offend the person. Well maybe what you can do like what the other responder said just move away slowly. i am sure once people start moving away from him or her, he should get the signal from there. Alternatively you can jus get him or her a perfume as gift. this not to offend him but just give it as a gift. you can do it for his birthday or something. anyway its nice giving someone a gift.
