I'll share a related story...
I used to work with my brother doing deliveries. At one place, we would have to park in the back, and then call the business and ask them to open the back door so we could load their items in their storage space. Then, we would want through the back and go to the front to have the shipments signed for.
One day, the back door is open. I think, "Cool. They are finally knowing when to expect us, and they will have the door open. Makes things easier and quicker." My brother and I load the shipments into the storage area, and then my brother stops, stands up and quickly runs out the back door. I don't know why he did it, until I started heading towards the front of the building. I was literally knocked a few steps back by an invisible foe... it smelled like someone gutted a rotten fish, left it out in the sun, and then slapped your face with it...
The smell got worse and worse as I got to the front of the store. I could barely speak; I was trying not to gag and I started coughing. Then, I noticed that the front doors of the building were also wide open. The owner of the place gave me a sorrowful look that said, "Yeah... I set off a turd bomb and it's so bad that I need to air the place out." I quickly got the signatures and left. Then, after being healed with fresh air, I started laughing the entire way to the next delivery stop.
