Okay I don't know what experience the people who rated him a "1" had, but they probably weren't the best patients. Yes, he's not a carebear out to fill the world with sunshine and rainbows. He's there to make your vision better and, in my experience, he has done so very well.
Yes, you do get a piece of paper that talks about him included with the standard paperwork that all medical practitioners give you. I don't think you're actually expected to read it, but clearly he feels that he is very good at what he does. I would suggest slipping in a compliment- it'll loosen him up a bit.
As far as the actual service rendered, I would put the value well above other doctors I've been to. This is for one reason- the follow-up appointment(s). You will pay for your initial appointment and then be scheduled for a follow-up appointment a week later. The follow-up will be very quick just to test the contacts he gave you the first time and be sure that your vision is correct with them, as well as to check up on any medical issues. If he makes any changes to your prescription, he will give you a new pair of contacts and then schedule another follow-up in a week. Once your prescription is finally perfect, you will order contacts. ALL follow-up visits are free. You pay for the right prescription, you get the right prescription- even if your pesky eyes keep adjusting with new contacts (like mine did).
Will I return? Yes.
