A furious customer spat in the face of a coffee shop worker when she refused to serve him because he had already been banned.
CCTV footage of the man's disgusting actions were posted online in a bid to identify the culprit.
He had first visited the Qualia coffee shop in Washington DC, in the USA, back in November.
The man had been wandering around asking staff to borrow a lighter, but was told no.
Assistant manager Allie Viall claims he shouted abuse at her and was a told not to come back.
