Too Much Oil?

I have a '91 Honda Civic 4dr, auto, EX with 75,000 miles on it. My non-Honda serviceman put too much engine oil in, to the tune of more than a quart of excess. I took it on a trip of about 200 miles, not noticing what was evident to outside persons. It started burning oil like crazy. It went from burning none to a quart in 1200 miles. My non-Honda serviceman says, "Big deal. The excess oils shouldn't hurt. It is done all the time." However, my Honda manual, in 1/4 inch large heavy type, says "Don't Overfill." Is my Honda's sudden burning of oil a consequence of the dealer's actions?
Well, one of the problems with adding too much oil is that you run the risk of blowing out your seals. For a mechanic to say that "its done all the time" is incorrect. Those small motors have limited oil carrying capacity. I believe that the older Hyundai's only had a capacity for 3 quarts. Put in too much, and where is it gonna go? Its going to find the weakest link and exploit it!
