Seems like your friend needs help.
I don't have a disc brake road bike but that's because I haven't bought a road bike in 11 years. I have ridden disc mountain bikes since 2008 and they have not been noisy except the current one does squeak when wet for a few seconds until the rotors dry a bit.
I think I can change the pads in under 5 minutes. I have changed them when heading out for a ride, doesn't take long at all.
