Banksy, The Doorman is not a nice man. He is a bully who stopped women entering the club, possibly to extort money from them. He is also a perv who likes to watch the women in the restrooms on CCTV. When Carys brought Matt into the restroom to have sex with him he enjoyed the spectacle until Matt was disintegrated, which ruined his fun somewhat. He alerted the police and told Torchwood the whole story.

Ceri Mears is a musician and stand up comic as well as an occasional actor with parts that include a notorious pot noodle advert.
