I had a training class this week where this guy sat next to me, and had rancid breath (it really smelled like a dirty diaper). He apparently didn't have good English, so as people were reading the handouts, he would be mumbling the words along for practice, but the worst part is that it was 90 degrees and the AC was broken, so the teacher had to use a fan which was - you guessed it - positioned so that his stank breath was being blown right into my nostrils
I didn't want to make a scene or embarrass him, so I just held my breath until he took pauses, then took deep inhales of fresh air, rinse and repeat
