I've been looking through my office "funny" file. I'll post a few more of these when I get home, but there was one where an Operator received a written complaint from a passenger because the "pull cord" on the bus was broken.
The operator wrote below the complaint: "The pull cord was not broken. Only the sound [My comment: This is the alarm sound that chimes when the cord is pulled, so the operator KNOWS the cord was pulled] was not working."
