We're really scratching our heads at this story! The PA system in this bingo hall has been continuously hijacked by a mystery singer, interrupting games with "incomprehensible screeching."
Could this be supernatural, or just a case of an incorrectly-routed microphone? Whatever the case, these hall owners aren't daunted, and carry on without their wireless mics.
Have you ever had or seen a snafu in your bingo hall quite like this? Let us know in the comments!
