this evening incarcerated once again behind that glass counter , with his weary form exhausted from the days hustle and bustle perched over a wooden stool and his aching head slumped over the counter top in front , with his dull listless eyes staring towards the entry of the shop and his tired fingers fiddling with the pen he used for jotting down orders , he seemed a person in dormancy who would kick in to full action at the first sight of a potential customer .
