I used to work with a woman that we all would have gladly killed because of gas problems. She was not embarrassed by it at all, in fact, I think that she was proud of it.
She would let one go and it smelled SO BAD that it would fill a room and clear it of anyone who could smell.
(she used to eat kelp and all other veggies that are good culprits for this kind of problem. I have also witnessed her eatting some things without appearing to chew, one apple, 5 bites.)
She also was very uncouth, her favorite habit was to lift one cheek off the chair and do the "aahhh, that's better" routine, and then your eyes started to water. (no joke)
We gave her a bottle of bean-o once, stuck an air freshener on the back of her chair, and had a can of spray, so we could blast back. Nothing sunk in with her. (yes, we realized at the time that we were not being very nice, but I have smelled pig poop that was LESS stinky)
She was also talked to by our plant boss about it, that is when she was given the bean-o (either she didn't take it or it didn't help)
Yeah - I can believe fights being started over this.
