HI ALL
many years ago i was on holiday in a different country,
i went to a library to do a research and they had a sharp sf-7300.
small but a very good copier,the technician was trying to fixit and he was sweeting for an hour and scratcing his head

i knew he was lost. so i ask him do you need any help,he looks at me and replies what the hell do you know old man.
moral of this true story,if someone offers you help at least hear what they have to say.

i am sure similar stories happened to you too
please share

cheers
