Here's the place the introduce yourself, post photos of your Fusion, Milan, MKZ, Zephyr and say hello!
As eGuru has pointed out, many modern cars require that the front bumper be removed for access to the head lamps. The focus for manufacturers is on ease of assembly at the factory. Unfortunately, for owners and the service industry, ease of service after sale is not always a priority. If I want to access the transmission dipstick in my MKZ, I'd have to move the intake out of the way, which requires tools to accomplish.
If you think that Ford is alone in this, here's a video of how to access the headlights on a 2012-2014 Toyota Camry. The procedure is quite similar to that of your Fusion. The Camry has been the best-selling sedan in the U.S. for several years now so there are, literally, millions of these cars on the road and they all will require front bumper cover removal for access to headlamps.
If you're going to avoid Ford for this reason when choosing your next car, you may be in for extensive research before purchase. Choose wisely.
I agree with eGuru. If all you had done was a bulb change, this seems excessive. Did you get a new headlight assembly? The service manual for my MKZ allows 1 hour of labor for headlamp bulb replacement, which also requires front bumper cover removal, and MKZs have adaptive headlamps, so it's a little more complicated than your Fusion. Even at $100/hr for labor (for argument's sake), it seems way out of line. What does it say on your service ticket?
