They dont know what they are doing.  the techs from Shaw@home cable internet service came to my house to give me a driver disk and the guy just plain opens the case while win 95 is on!!!  What a f***ing idiot!!!  He could have fried my computer with all the static elctricity in that room or something else.  I think he should have been fired and then when he takes out an old network card hes like "oh dont touch the circuit board.  grab the metal connector"  I was ready to backhand him accross the head if I wasnt such a nice person.  That pissed me off!
