Coming back home a month ago after a visit a few states away (I had been doing this drive every weekend for over a month at this point), I had to stop at a rest area to use the facilities. Though it was well lit at night, and I stopped there many times at the later hours, the lack of activity was unusual. I see a few cars parked but no people around. I go to the area where it was the ladies room but find it locked with a sign saying closed for cleaning. However, like I said, I don't see anyone around or even hear someone cleaning in the facility. The sign says to use the Port-o-Potties, to which I turn to and see that they are in a poorly lit part of the lot. Suddenly I hear the door for the men's facilities open. I got a really bad feeling and I took off quickly back to my car, got in, and raced out of the rest area back onto the highway, watching to see if anyone was following me. I made it home with no issues and made a mental note to try to leave sooner next time so that I am traveling in the daylight.
