"rape their customers"

Lovely. Absolutely lovely.

Mark, you may be upset, but sexual assault is not the right image for a business letter, y'know.

Of course, since you were a repair tech, isn't this something you could do yourself? I'm no camera expert, but a bottle of cleaner, a soft cloth, maybe a brush... these can be purchased at a camera store for what, under $10?

Which, of course, backs up your point. But if it was something that you could do in 10 minutes for less than $10, why even bother with Canon? Claims of "free" or no, I can't imagine mailing my camera away if I could just do it myself.
