I pulled into a Pilot truck stop off I-85 yesterday to use the bathroom. The door was propped open, so I peeked in, and a woman was there cleaning. She said, "Oh, come on in." So, I did. But she never left. I stopped and looked at her for a second, so she motioned back to the stalls with the doors. She said, "You can use those." I really had to go—could no longer suppress the bottle of water from a few hours before—so I went.
She was still in there sweeping when I walked out.
Cleanest bathroom I used all day.
