A country store where I grew up as a kid had a loudspeaker mounted to the outside back of the toilet. The guy had it powered with a PA system in his store, and the outhouse could be seen from the store side window. When a lone woman would stop on a trip to use the facility, he would wait the right amount of time, then use the speaker to tell her “hey lady, I can’t see down here!” or other such nonsense. They would come out screaming and pulling their pants up as they flew back to the car. The crowd of guys hanging out in the store would be howling with laughter. Some irate husband came back to the store after an incident and had it out with the guy. That ended the toilet “fun”.
