Caffeine(2007)

A fanciful battle of the sexes ensues when the relationships of the staff and patrons of a quirky London cafe are unexpectedly turned upside down by sudden revelations of terribly embarrassing secrets having to do with their sexual misadventures: A neurotic young commitment-phobe runs into his ex-girlfriend while he's whacked out on killer dope; a high strung control freak finds out that her husband-to-be is a transvestite; a hyper-possessive boyfriend discovers that his girlfriend is an ex-porn actress; and the manager's boyfriend has a menage a trois which he says is forgivable because the girls were identical twins.
