Turn it off, Eugene

"Bathroom?" the guy said.
I assumed that he actually meant "Pardon me, good sir, but does this library have a public restroom?" so I gave him directions.
"DO YOU HAVE A BATHROOM" he said, kinda loud. I saw the earbuds and heard the music at about the same time. If I was totally committted to customer service to all, even inconsiderate jerks, I could have pointed to the restrooms. But I'm kinda passive aggressive. So I repeated my directions, even softer this time, finally forcing the buds out of his ears. He repeated his question/demand and I repeated my directions. The buds went in, and off he went (sans thank you).
A moment later I heard him closer to the bathroom, hollering "DO YOU HAVE A BATHROOM" at somebody else.
