This'll seem unnecessarily mean but is the truth. Back when I was 18 and working as a cashier, a man and his son, both extremely overweight, went through my line. Idk what was wrong with them, but they both STANK so hard I could taste it. I went home and showered and could still smell it. I could smell it on my clothes so I washed them too. It was so horrible. I could smell it for hours. It was like the smell had been burned into the back of my nose.

To this day, if I smell something similar to that smell I remember that day and start to panic a little.
