I’m sure also little baby special snowflakes who don’t want to be bothered getting out of the pool or lake, etc., to use the bathroom.
True that!
Though there is no such thing as a urine-detecting dye, you can purchase signs that prey upon the misconception that a urine indicator exists. The signs, which warn the pool is being monitored with a chemical “wee alert,” are believed to be an effective deterrent against urination in a pool, particularly with adult swimmers.
