the bar keeper had made no attempt to make martin and ghiliba vacate his premises , on the contrary , he had left a complimentary bottle of cheap whisky and two small shots glasses within reach of his final two patrons , and had murmured something to ghiliba in a gutteral-sounding language which martin did not understand , but which seemed to interpret into an invitation to remain , before disappearing behind a screen into a room beyond the bar , and presumably his bed .
