I would note also that while he calls the other person a "professional" as they dont say who it was.. we really dont know that they are a professional.
we also dont know what the pro charged. $10 or $400.. we dont know what he charged to re do them all either.,.
someone might be a professional, but have someone say, i only want to spend $50, what can you do for me, and only later regret this and fork out more money... but no longer trust the work of the first person
if the person really is that bad and a professional, why not say who it was to save others from a bad experience.
