My 1st “pro” job I had some pals down the hall in the “big office”, with 4 people. The oldest of them (maybe 50s) was infamous as a flatulator. I didn’t know this until I asked what the deal was with all of them having dust masks hanging from their lamps. That’s when I found out they were symbolic of using protection against Tom and his frequent outbursts.
I remember reading a post a while back, where a person talked about working in a gov office with a group of deaf people who have no idea that passing gas causes sound. I can’t do his description justice although it still brings a smile to my face when I think about it.
