Question about someone farting in my office?

Some guy comes into my office/cubicle. He is eating Whataburger. It stinks. Then after about fifteen minutes he lets out about 3.6 cu. ft. of air. A genuine effluvium for the ages. Here is my damn question. Why did it smell exactly like that whataburger that went in him? that pisses me off. So i'm sitting there trying to decide if I should run out the door and jump in traffic to escape. I don't like tomatoes and all of a sudden I take a whiff and it is like someone slapped me directly across the nose and left eye with a freshly cut tomato slice covered in mustard on one side and pickle juice on the other. I grab the scotch tape and use half a roll taping a wad of paper towels around my nose since I'm typing and can't leave. After another minute or so it is as if someone has taking 6 and a half of those small chip pickles directly up my nose choking off every ounce of life I still have remaining in me. I am trying to decide if i should bludgeon myself with my red Swing line stapler or choke myself with the chord. At this point i'd rather have a concussion or staple my nostrils shut. And superglue my eyelids shut while i'm at it. Then he let out another one and it made a crazy noise that sounded like a large piece of lettuce was trapped half in and half out of his *** slapping back and forth like an exploded balloon.
