<human>: Can you succinctly summarize the text in 1-3 sentences?

**Preface**:

I burp a lot. I don't even think about it or consider it disgusting in any way.  I hardly notice when I or other people burp.  It's a natural bodily function. Shit happens. 

**Explanation**:

This co-worker (let's call her Stacy), who only started this job a month or so ago, recently told everyone that she's disgusted by/horrified of burps.  This only came to light because another co-worker burped while in the same room as Stacy, and she ran out of the room gagging, fell, and scraped her knee.  It was then announced to the staff that we weren't allowed to burp near her or "mess with Stacy because of her...problem." 

Fast forward to yesterday.  I was sitting in the break room, eating Cheezits and Dr. Pepper and minding my own business.  Stacy was sitting two chairs away.  I let out the teensiest of burps, and half a second later Stacy had backhanded me across the face. Dafuq. Then she said, "I didn't even hit you that hard!" 

I silently left the room with a red hand print on my cheek.

Six of our co-workers saw it, a supervisor found out, and our main boss forced Stacy to apologize to me and told her she'd be fired if something similar happened again. She said her depth perception was off, she didn't mean to hit me *that* hard, and would work on her "problem" to avoid another "episode"... generic, scripted, bullshit apology.
<bot>: Got slapped in the face by co-worker for burping, she was forced to apologize by our boss and put on probation. What  weird phobias have you seen that have gotten you/people you know into trouble?
