PARKLAND, Wash. -- The barista who threw a cup of boiling water on a flasher said he was the strangest customer she’s ever had.

Kylie Ross said she was more freaked out than scared of a flasher at the Parkland Java Girls espresso stand.

“So I opened the window and there is this man dressed in bra and panties, touching himself inappropriately,” Ross said.

Surveillance video from the espresso stand shows the reaction of Ross and her co-worker Jamae Feddock -- as a man dressed in women's underwear exposes himself after pulling into the drive through.

On his third trip to the window -- Ross tossed a cup of boiling hot water on the man's chest.

“I know he was hurting cause when we get a little droplet of water on us, it stings,” Ross said. “I drenched him in water, so I know he was in pain.”

Baristas said these kinds of incidents are becoming more common.

“At the Auburn stand of Java Girls, some guy came through doing something similar,” said Sharia Feddock, Jamae's sister.

Sharia said things like this don't just happen to bikini baristas. She was flashed when she was working in jeans and a T-shirt.

Sharia said she doesn’t think the flashing incidents have anything to do with being a bikini barista.

Pierce County sheriff's investigators said they have a possible suspect identified in this case, but so far no arrest has been made.
