The Flagler County Sheriff's Office said a man pulled up to the drive-in lane at RBC Bank in Palm Coast about 8:50 a.m. Thursday and asked if he could buy a money order, the Orlando Sentinel reported Friday.
The man became upset when the teller told him money orders were not available and drove away a few moments later.
The next customer at the drive-in picked up the tube and liquid -- believed to be the man's urine -- spilled onto her lap and the interior of her vehicle.
Deputies said they are working to identify a suspect and he could be charged with a misdemeanor count of causing a nuisance injurious to health.
