This question already has an answer here:
I have a co-worker who stands behind me at work, our desks face away from each other with a few feet between.
For the last month I have heard audible farts at least once per day, and several people sitting near me have smelled them 2-4 times per day.
Having a direct conversation could be awkward because he is not a peer, he is a manager. Any suggestions on how to deal with this?
edit: I think this is different from the hygiene question because the roles are reversed. I am not a manager of the person in question, they are the manager
