PORTLAND — A Portland bikini barista says she followed a man who stole her tips onto a bus and demanded that he give the money back.

Molly Karvinen tells KATU-TV that the man first offered her “a couple of bucks” but she demanded the rest as stunned bus passengers watched. The bus driver told her to take the dispute elsewhere.

She says the man finally gave her back about $20 before she got off the bus. She estimates he took about $50.

Police are looking for the man.
