xerox machine 's technican

on 1st day of this month, the technican came to have the check and clean service. (once or twice a year here but every month for cityu's library). i think they are much better than me. 1st everyone hurrys to use the machine again but they don't care. they just follow the sequence to work even under such pressure. 2nd is my main weak point comparing with. i.e. don't look around and attach to the things unrelated. i hear the voice and i will look at that way if i'm not very concentrated (pressurized) on the job. too bad i am.
