First job out of college, we had this older engineer, probably late 50s, early 60s. Anyway, my first real work trip out of town was with him. We'll call him Steve because that was his name. We're flying Omaha to Denver to Vancouver. We land in Denver and proceed to walk to our next gate. Steve proceeds to fart, quite loudly I might add, all the way through the airport. And DEN is a looooong airport.
The first time, I'm like "Oh my, that's embarrassing for him." Then it kept happening and I realized "he just doesn't care!"
As I worked at that company for many more years, I learned Steve was notorious for farting with reckless abandon and was well-known for not washing his hands and taking candy from the community jar.
