It's not work, but when I was at BYU, I dreaded going to the testing center during the winter. People would be sniffing and clearing their throat etc. all around.

I remember a particular instance where I was taking a test that should have taken about 45 min. It took me about 2 hrs. I could not concentrate. I threw a small package of Kleenex at one guy because he would sniff every 3 seconds.
