Accord Brake Fluid & Transmission Fluid Problems ?

Hello:

My son has a 6 cyl 2005 Accord.
Has 28,000 miles on it.

He brought it in to the Honda Dealership for an oil change, and they told
him that the
Brake Fluid, and also the Transmission Fluid, was "dark and dirty", and both
should be replaced next time he comes in for an oil change (probably after
another 7,500 miles)

I have always felt that this Dealership has a tendency to "milk" maintenance
items.

Do the two fluid problems they mentioned sound reasonable after only 28K ?

If so, what might be the causes of ?

BTW: just a thought here, but how could they even see the brake fluid
without bleeding the lines ?
Can one tell from the fluid in the reservoir ?

Thanks,
Bob
