Don't get me started. The ones I had experience with in The Netherlands were also terrible. On a MacBook Air 2012, my 'f' key would always get stuck. I went to our local Apple authorized service provider, which was also the store where I bought the MacBook Air.
First they tried to put the blame on me, arguing that I removed the keycap before (I didn't). When they were finally willing to repair the laptop, they first gave me a lecture about how I should thank them for making an exception, because they were not obliged to repair the keyboard if I damaged the key by removing a keycap (which again, I didn't).
Most of them haven't been very ethical in their business — I've heard numerous cases of the authorised providers charging for additional labour and parts to replace an out-of-warranty MacBook battery, while the Genius Bar does it for a flat fee [1].
